Subject: [PATCH 003/507] iio:trigger: Remove necessity to have a trig->ops
structure.
There are a few cases where none of the callbacks are supplied and the
ops structure purely existed to provide the driver module.
Given that is done differently now, we don't need to have a trig_ops structure.
Allow for it not being there required a few additional sanity checks when
trying check if particular callbacks are set.

The equivalent of both of these are now done via macro magic when

From 6c5bffa80ecae54c3ddd113eb4d93382503989be Mon Sep 17 00:00:00 2001
From: Jonathan Cameron <jic23@kernel.org>
Date: Sun, 23 Jul 2017 17:25:48 +0100
Subject: [PATCH 005/507] iio:accel: drop assign iio_info.driver_module and
iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.

The equivalent of both of these are now done via macro magic when

Clearly this set jumps across multiple areas, but inherently it
can't be grouped like the other sets in this series so I've done
all the stuff in the common directory together.

From 13a8c6c2a1138309dcf7744cb4db7aea54d8085a Mon Sep 17 00:00:00 2001
From: Jonathan Cameron <jic23@kernel.org>
Date: Sun, 23 Jul 2017 17:25:58 +0100
Subject: [PATCH 015/507] iio:humidity: drop assign iio_info.driver_module and
iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.

From 7f307262af08e842297561ef7afd3cce248b258a Mon Sep 17 00:00:00 2001
From: Jonathan Cameron <jic23@kernel.org>
Date: Sun, 23 Jul 2017 17:26:01 +0100
Subject: [PATCH 018/507] iio:magnetometer: drop assign iio_info.driver_module
and iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.

The equivalent of both of these are now done via macro magic when

The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.
Note that stm32-timer-trigger has expanded rather beyond triggers
(to include encoder input counting for example) and hence has an
iio_info structure.

Subject: [PATCH 035/507] staging:iio:light:tsl2x7x drop assignment of
driver_module
The equivalent is now done via macro magic in the register call.
Note this is the only case not found by the coccinelle script
suggesting that perhaps that script needs to be a little more
clever!

Subject: [PATCH 056/507] drivers: misc: ti_dac7512: Remove duplicate driver
The Texas Instruments DAC7512 has the exact same pinout, programming
interface and power-down modes as the Texas Instruments DAC121S101 and
Analog Devices AD5320, which are already supported by the IIO driver
ad5446.c. Remove the duplicate misc driver.
This requires user space to migrate to the standardized IIO sysfs ABI.
(In other words, it needs to change a filename.)
The IIO driver supports the chip's features more fully, e.g. the ability
to power down the output or choose one of the available powerdown modes.
There is an oddity with the misc driver in that it initializes the SPI
slave to SPI_MODE_0, in contradiction to the datasheet which specifies
that data is latched in on the falling edge, implying that SPI_MODE_1
or SPI_MODE_2 must be used. Another oddity is that Kconfig and the
MODULE_DESCRIPTION() claim the chip has 16-bit resolution although it
actually has 12-bit.

Subject: [PATCH 057/507] iio: accel: mma8452: improvements to handle multiple
events
This driver supports multiple devices like mma8653,
mma8652, mma8452, mma8453 and fxls8471. Almost all
these devices have more than one event.
Current driver design hardcodes the event specific
information, so only one event can be supported by this
driver at any given time.
Also current design doesn't have the flexibility to
add more events.
This patch improves by detaching the event related
information from chip_info struct,and based on channel
type and event direction the corresponding event
configuration registers are picked dynamically.
Hence both transient and freefall events can be
handled in read/write callbacks.
Changes are thoroughly tested on fxls8471 device on imx6UL
Eval board using iio_event_monitor user space program.
After this fix both Freefall and Transient events are
handled by the driver without any conflicts.

Subject: [PATCH 059/507] staging: rts5208: fix gcc-8 logic error warning
As gcc-8 points out, the bit mask check makes no sense here:
drivers/staging/rts5208/sd.c: In function 'ext_sd_send_cmd_get_rsp':
drivers/staging/rts5208/sd.c:4130:25: error: bitwise comparison always evaluates to true [-Werror=tautological-compare]
However, the code is even more bogus, as we have already
checked for the SD_RSP_TYPE_R0 case earlier in the function
and returned success. As seen in the mmc/sd driver core,
SD_RSP_TYPE_R0 means "no response" anyway, so checking for
a particular response would not help either.
This just removes the nonsensical code to get rid of the
warning.

Subject: [PATCH 066/507] staging: ccree: Replace kzalloc with devm_kzalloc
It is recommended to use managed function devm_kzalloc, which
simplifies driver cleanup paths and driver code.
This patch does the following:
(a) replace kzalloc with devm_kzalloc.
(b) drop kfree(), because memory allocated with devm_kzalloc() is
automatically freed on driver detach, otherwise it leads to a double
free.
(c) remove unnecessary blank lines.

Subject: [PATCH 067/507] staging: ccree: Convert to devm_ioremap_resource for
map, unmap
It is recommended to use managed function devm_ioremap_resource(),
which simplifies driver cleanup paths and driver code.
This patch does the following:
(a) replace request_mem_region(), ioremap() and corresponding error
handling with devm_ioremap_resource().
(b) remove struct resource pointer(res_mem) in struct ssi_drvdata as it
seems redundant, use struct resource pointer which is defined locally and
adjust return value of platform_get_resource() accordingly.
(c) release_mem_region() and iounmap() are dropped, since devm_ioremap_
resource() releases and unmaps mem region on driver detach.
(d) adjust log messages accordingly and remove any blank lines.

It is recommended to use managed function devm_request_irq(),

This patch does the following:
(a) replace platform_get_resource(), request_irq() and corresponding
error handling with platform_get_irq() and devm_request_irq().
(b) remove struct resource pointer(res_irq) in struct ssi_drvdata as
it seems redundant.
(c) change type of member irq in struct ssi_drvdata from unsigned int
to int, as return type of platform_get_irq is int and can be used in
error handling.
(d) remove irq_registered variable from driver probe as it seems
redundant.
(e) free_irq is not required any more, devm_request_irq() free's it
on driver detach.
(f) adjust log messages accordingly and remove any blank lines.

The resource release on probe/init error was being handled
in an awkward manner and possibly leaking memory on certain
(unlikely) error path.
Fix it by simplifying the error resource release and making
it easier to track.

Subject: [PATCH 076/507] staging: rtlwifi: remove unused functions
Functions rtl_rfreg_delay() and rtl_bb_delay() are unused within the
driver. Both functions call rtl_addr_delay(), this function is unused
outside of these call sites.The driver (and kernel) code base is cleaner
if unused functions are removed.
Remove unused functions.

a union recv_frame by using LIST_CONTAINOR. Just use a direct cast
to union recv_frame instead.

Subject: [PATCH 085/507] Staging: speakup: Replace symbolic permission
Replace S_IRUGO by 0444 in module parameter declaration. 0444 is more
readable and matches the style used in other declarations nearby.
Problem found using checkpatch.

Subject: [PATCH 096/507] Staging: rtlwifi: Remove unnecessary 'out of memory'
message.
Logging messages that show some type of "out of memory" error
are generally unnecessary as there is a generic message and
a stack dump done by the memory subsystem.
These messages generally increase kernel size without much
added value.
Problem found by checkpatch.

Subject: [PATCH 101/507] staging: wlan-ng: Avoid bogus endianness
The linkstatus variable in the info struct received as __le16
but handled in every other place in the driver as u16
Fix that and remove the sparse warning that occurred due to it:
prism2sta.c:1450:29: warning: incorrect type in assignment (different base types)
prism2sta.c:1450:29: expected unsigned short [unsigned] [usertype] link_status_new
prism2sta.c:1450:29: got restricted __le16 [usertype] linkstatus

Subject: [PATCH 107/507] staging: lustre: lnet: Replace list_for_each with
list_for_each_entry
Replace use of the combination of list_for_each and list_entry
with list_for_each_entry to simplify the code and remove variables
that are used only in list_for_each.
Issue found and corrected using Coccinelle script:

type T1, T2, T3;
iterator name list_for_each, list_for_each_entry;
identifier pos, var;
@@

Subject: [PATCH 118/507] Staging: irda: drivers: Move the curly bracket to the
same line as if
Move the left curly brace to the same line as the if statement.
This coding style is more common and also reduces the number of
lines of code.

Subject: [PATCH 140/507] staging: rtl8188eu: Fix spelling
rtl8188eu contains some spelling errors in comment lines as well as in
constants. Harmless as they are, they still make the code feel a bit
unclean, which is not something we want in the kernel.
Improve this by fixing typos so they won't catch eyes of future driver
developers anymore.

Remove unnecessary messages because OOM (Out Of Memory Manager)
reports memory allocation fail messages. The return value

Subject: [PATCH 148/507] Staging: irda: net: Do not initialise statics to NULL
There is no need to initialize static variables to NULL
because they are stored in .bss segment. This segment
is initialized to 0 at the beginning of the code execution.
Issue found by checkpatch.pl.

Subject: [PATCH 157/507] iio: adc: mcp320x: Speed up readout of single-channel
ADCs
Single-channel converters such as mcp3001, mcp3201, mcp3301 and the
upcoming mcp3550/1/3 lack a MOSI pin, so there's no need to call
mcp320x_channel_to_tx_data() for them.
Moreover, instead of calling spi_read() for these converters, which
generates an spi_message and spi_transfer on the stack on every readout,
it's more efficient to use the spi_message and spi_transfer[] included
in struct mcp320x (as we do for multi-channel ADCs), but initialize the
spi_message only with the receive transfer.

Subject: [PATCH 160/507] staging: iio: tsl2x7x: clean up limit checks
The background of this code is that we can either use the default
tables or load our own table with sysfs. The default tables are three
element arrays of struct tsl2x7x_lux. If we load the table with sysfs
then we can have as many as nine elements. Which ever way we do it, the
last element is always zeroed out.
The most interesting part of this patch is in the
in_illuminance0_lux_table_show() function. We were using the wrong
limit, "TSL2X7X_MAX_LUX_TABLE_SIZE * 3", when it should have been just
"TSL2X7X_MAX_LUX_TABLE_SIZE". This creates a static checker warning
that we are going of bounds. However, since the last element is
always zeroed out, that means we hit the break statement and the code
works correctly despite the wrong limit check.
I made several related readability changes. The most notable that I
changed the MAX_DEFAULT_TABLE_BYTES define which was:
I renamed the define to TSL2X7X_DEFAULT_TABLE_BYTES because it's not the
max size, it's the only size. Also the size should really be expressed
as sizeof(struct tsl2x7x_lux) * 3. In other words, 12 * 3 instead of
4 * 9. It's 36 bytes either way, so this doesn't change the behavior.
Finally, I created the TSL2X7X_DEF_LUX_TABLE_SZ define instead of using
the magic number 3. I declared the default tables using that define
to hopefully signal to future programmers that if they want to use a
different size they have to update all the related code.

Subject: [PATCH 165/507] Staging: iio: meter: ade7759: update locking method
for write frequency
iio_dev->mlock is to be used only by the IIO core for protecting
device mode changes between INDIO_DIRECT and INDIO_BUFFER.
This patch replaces the use of mlock with the already established
buf_lock mutex.
Introducing an 'unlocked' spi_write_reg_16 function to be used by
ade7759_write_frequency avoids nested locks and maintains atomicity
between bus and device frequency changes.
Based on the solution found in ade7754 patch here:

Subject: [PATCH 167/507] dt-bindings: iio: adc: mcp320x: Update for
mcp3550/1/3
All chips supported by this driver clock data out on the falling edge
and latch data in on the rising edge, hence SPI mode (0,0) or (1,1)
must be used.
Furthermore, none of the chips has an internal reference voltage
regulator, so an external supply is always required and needs to be
specified in the device tree lest the IIO "scale" in sysfs cannot be
calculated.
Document these requirements in the device tree binding, add compatible
strings for the newly supported mcp3550/1/3 and explain that SPI mode
(0,0) should be preferred for these chips.

Subject: [PATCH 172/507] iio:stm32-lp-timer and ep93xx: drop assign
iio_info.driver_module and iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements have gone away.

Subject: [PATCH 176/507] staging: unisys: visorbus: don't need local variable
cmd
The local variable cmd was just being used to dereference a field inside
of it. Get rid of the variable and just derefernce the parameter being
passed in.

Subject: [PATCH 184/507] staging: unisys: visorbus: don't put code in
declaration.
Simplify the code by not putting the assignment in the declaration. Define
it and then assign it, so the function doesn't get bunched up on the
right.

Subject: [PATCH 186/507] staging: unisys: fix up device_destroy
Visorbus_remove_instance calls device_unregister which in turn will call
visorbus_release_busdevice. The function visorbus_release_busdevice was
freeing the visor_device. The code in visorbus_remove_instance was then
trying to reference the visor_device. This patch cleans up the code so
the visor_device is not referenced after the unregister.

Subject: [PATCH 213/507] staging: unisys: visorbus: simplify
visorchannel_create_guts
Removing the two wrapper functions dealing with visorchannel_create() and
instead just always use a new version of visorchannel_create() with an
additional parameter.

the volatile fields of bcm2835_alsa_stream -
control and status are not used.
$ grep bcm2835_alsa_stream
>From the above command all instances we see that
all variables of 'bcm2835_alsa_stream' are declared as
'alsa_stream'
So search for 'control' wherever we have 'alsa_stream'
$ grep -l 'alsa_stream' | xargs grep "control"
The above command returns where we don't any usage of
'control' field. which means that there is no usage of
these fields.
similarly for 'status' we see no usages.

Subject: [PATCH 235/507] staging: rtl8188eu: remove implicit bool->int
conversions
Implicit type conversions are bad; they hinder readability of code and have
potential to cause bugs. Here the variable wait_ack is always supplied a bool
value while in function declarations it is defined as an int type. Fix it by
defining wait_ack a bool type in all usages.

Using typedef will hide that 'DPMS_t' is enum. Removing this
will make sure that we are actually working with enum. Also it is
not a good coding style to use typedef
In this commit remove typedef and lowercaser the name 'DPMS_t'. And
also drop '_t' which traditionally means typedef.

From a55ef6f52fdd5a4538dc140903416361d156c548 Mon Sep 17 00:00:00 2001
From: Gilad Ben-Yossef <gilad@benyossef.com>
Date: Tue, 3 Oct 2017 11:42:15 +0100
Subject: [PATCH 257/507] staging: ccree: simplify access to struct device
Introduce a function to retrieve struct device from private
data structure in preparation to replacing custom logging
macros with proper dev_dbg and friends which require struct
device.

Subject: [PATCH 261/507] staging: fsl-mc/dpio: Fix incorrect comparison
For some dpio functions, a cpu id parameter value of -1 is
valid and means "any". But when trying to validate this param
value against an upper limit, in this case num_possible_cpus(),
we risk obtaining the wrong result due to an implicit cast.
Avoid an incorrect check result by explicitly comparing the
cpu id with the "any" value before verifying the upper bound.

MIME-Version: 1.0

Using the ARRAY_SIZE macro improves the readability of the code. Also,
it is useless to use a variable to store this constant calculated at
compile time.
Found with Coccinelle with the following semantic patch:
@r depends on (org || report)@
type T;
T[] E;
position p;

(sizeof(E)@p /sizeof(*E))

Subject: [PATCH 263/507] staging: rtl8723bs: use ARRAY_SIZE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Using the ARRAY_SIZE macro improves the readability of the code. Also,
it is not always useful to use a variable to store this constant
calculated at compile time.
Found with Coccinelle with the following semantic patch:
@r depends on (org || report)@
type T;
T[] E;
position p;
@@
(
(sizeof(E)@p /sizeof(*E))
|
(sizeof(E)@p /sizeof(E[...]))
|
(sizeof(E)@p /sizeof(T))
)

Subject: [PATCH 264/507] staging: rtl8192u: make r8192_wx_handlers_def
structure const
Make this const as it is only stored in a const field of a pci_dev
structure. Make the declaration in the header const too.
Structure found using Coccinelle and changes done by hand.

Subject: [PATCH 267/507] staging: rtl8192u: Fix some error handling path
If 'rtl8192_usb_initendpoints()' fails, it may have allocated some
resources that need to be freed. The corresponding is propagated up to
'rtl8192_usb_prob()'. So, in this function if an error
code is returned by 'rtl8192_init()' we should call
'rtl8192_usb_deleteendpoints()'.
Some error handling code is also duplicated in 'rtl8192_init()' and in
'rtl8192_usb_prob()'. This looks harmless because the freed pointers are
set to NULL but it looks confusing.
Fix all that by just moving the 'fail' label and removing duplicated
error handling code from 'rtl8192_ini()'. All this resources freeing will
be handled by 'rtl8192_usb_prob()' directly.
The calling graph is:
rtl8192_usb_probe
--> rtl8192_init
--> rtl8192_usb_initendpoints

Subject: [PATCH 274/507] staging: ccree: Convert to
platform_{get,set}_drvdata()
Platform devices are expected to use wrapper functions,
platform_{get,set}_drvdata() with platform_device as argument,
for getting and setting the driver data. dev_{get,set}_drvdata()
are using &plat_dev->dev.
For wrapper functions we can directly pass a struct platform_device.
dev_set_drvdata() is redundant and therefore removed. The driver core
clears the driver data to NULL after device_release or on probe failure.

Subject: [PATCH 278/507] iio: adc: sun4i-gpadc-iio: register in the thermal
after registering in pm
This driver has a get_temp function used by the thermal framework that
uses pm functions.
However, the driver isn't registered in pm before it is registered in
thermal framework, resulting in the pm_resume not being called and thus
the IP not enabled.
When the IP is disabled, the raw temp value is always 0. With the
devices currently supported, it isn't a problem since with their
respective formula, they return a really cold SoC temperature which
isn't a problem for the thermal framework. But for future SoC that have
a different formula, it could return a critically hot temperature,
forcing the thermal framework to shutdown the board.

Subject: [PATCH 279/507] iio: adc: sun4i-gpadc-iio: do not fail probing when
no thermal DT node
Before this patch, forgetting to put a thermal-zones DT node would
result in the driver failing to probe.
It should be perfectly acceptable to have the driver probe even if no
thermal-zones DT is found. However, it shouldn't want to fail if the
thermal registering fail for any other reason (waiting for other drivers
for example) so check on ENODEV only.

This improves code uniformity (range checks for als_gain are also done
in the setter). Also unmangle rounding and calculation of register value.
The calculated integration time it_ms is required in the next patch of
the series.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit
The reported scale was only correct for the default settings of 100 ms
integration time and gain 1.
This aligns the reported scale with the behaviour of any other IIO driver
and the documented ABI, but may require userspace changes if someone uses
non-default settings.

Subject: [PATCH 291/507] staging: iio: tsl2x7x: rename tsl2x7x_settings
variable to settings
The length of the 'tsl2x7x_settings' variable within the tsl2X7X_chip
structure makes some of the line lengths greater than 80 characters for
upcoming patches. This patch shortens the name of the 'tsl2x7x_settings'
variable in this structure to just 'settings' to improve code
readability.

From 4546813a7f6b3dc67ac258666092b1952c4e2ea1 Mon Sep 17 00:00:00 2001
From: Brian Masney <masneyb@onstation.org>
Date: Fri, 29 Sep 2017 21:09:20 -0400
Subject: [PATCH 292/507] staging: iio: tsl2x7x: migrate
in_illuminance0_integration_time sysfs attribute to iio_chan_spec
The driver explicitly creates the in_illuminance0_integration_time sysfs
attribute outside the IIO core. This attribute is available in the IIO
core so this patches migrates the attribute to be created by
the iio_chan_spec.

Subject: [PATCH 294/507] staging: iio: ade7753: expanding buffer lock to cover
both buffer and state protection
Dropping the extra lock (used for protecting the write frequency) by
expanding the buffer lock to cover both buffer and state protection.
Doing this by introducing a new function (__ade7753_spi_write_reg_16)
making buffer changes without locking the state, to avoid nested locks
while making device frequency changes.

Subject: [PATCH 299/507] iio: imu: st_lsm6dsx: split fifo mode and fifo odr
configuration
Separate fifo mode and max fifo sample rate configuration.
That change will be necessary to reuse st_lsm6dsx_set_fifo_mode()
routine and to support more devices in st_lsm6dsx driver

Subject: [PATCH 302/507] iio: adc: ina2xx: Adhere to documented ABI, use Ohm
instead of uOhm
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
According to the ABI documentation, the shunt resistor value should be
specificied in Ohm. As this is also used/documented for the MAX9611,
use the same for the INA2xx driver.
This poses an ABI break for anyone actually altering the shunt value
through the sysfs interface, it does not alter the default value nor
a value set from the devicetree.
Minor change: Fix comment, 1mA is 10^-3A.

Subject: [PATCH 303/507] staging: iio: adc: ad7192: use driver private lock to
protect hardware state changes
The IIO subsystem is redefining iio_dev->mlock to be used by
the IIO core only for protecting device operating mode changes.
ie. Changes between INDIO_DIRECT_MODE, INDIO_BUFFER_* modes.
In this driver, mlock was being used to protect hardware state
changes. Replace it with a driver private lock.
Also, as there are state changes in the ad7192_ write_raw function, a lock
is added to prevent the concurrent state changes.

Subject: [PATCH 304/507] iio: adc: mcp320x: Add support for mcp3550/1/3
These ADCs are marketed as single-channel 22 bit delta-sigma ADCs, but
in reality their resolution is 21 bit with an overrange or underrange
of 12% beyond Vref. In other words, "full scale" means +/- 2^20.
This driver does not explicitly signal back to the user when an
overrange or underrange occurs, but the user can detect it by comparing
the raw value to +/- 2^20 (or the scaled value to Vref).
The chips feature an extended temperature range and high accuracy,
low noise characteristics, but their conversion times are slow with
up to 80 ms +/- 2% (on the MCP3550-50).
Hence, unlike the other ADCs supported by the driver, conversion does
not take place in realtime upon lowering CS. Instead, CS is asserted
for 8 usec to start the conversion. After waiting for the duration of
the conversion, the result can be fetched. While waiting, control of
the bus is ceased so it may be used by a different device.
After the result has been fetched and 10 us have passed, the chip goes
into shutdown and an additional power-up delay of 144 clock periods is
then required to wake the analog circuitry upon the next conversion
(footnote below table 4-1, page 16 in the spec).
Optionally, the chips can be used in so-called "continuous conversion
mode": Conversions then take place continuously and the last result may
be fetched at any time without observing a delay. The mode is enabled
by permanently driving CS low, e.g. by wiring it to ground. The driver
only supports "single conversion mode" for now but should be adaptable
to "continuous conversion mode" with moderate effort.
The chips clock out a 3 byte word, unlike the other ADCs supported by
the driver which all have a lower resolution than 16 bit and thus make
do with 2 bytes. Calculate the word length on probe by rounding up the
resolution to full bytes. Crucially, if the clock idles low, the
transfer is preceded by a useless Data Ready bit which increases its
length from 24 bit to 25 bit = 4 bytes (section 5.5 in the spec).
Autosense this based on the SPI slave's configuration.

Subject: [PATCH 305/507] iio: st_sensors: add register mask for status
register
Introduce register mask for data-ready status register since
pressure sensors (e.g. LPS22HB) export just two channels
(BIT(0) and BIT(1)) and BIT(2) is marked reserved while in
st_sensors_new_samples_available() value read from status register
is masked using 0x7.
Moreover do not mask status register using active_scan_mask since
now status value is properly masked and if the result is not zero the
interrupt has to be consumed by the driver. This fix an issue on LPS25H
and LPS331AP where channel definition is swapped respect to status
register.
Furthermore that change allows to properly support new devices
(e.g LIS2DW12) that report just ZYXDA (data-ready) field in status register
to figure out if the interrupt has been generated by the device.
Fixes: 97865fe41322 (iio: st_sensors: verify interrupt event to status)

Subject: [PATCH 306/507] iio: st_sensors: decouple irq1 configuration
parameters from the irq2 ones
Separate data-ready configuration parameters for INT1 and INT2 pins in
st_sensor_data_ready_irq data structure. That change will be use to
properly support LIS2DW12 accel sensor.

Subject: [PATCH 307/507] iio: st_sensors: do not always write enable_axis
register
New devices (e.g. LIS2DW12) enable all axis by default and do not export
that capability in register map. Check if the enable_axis register
address has been declared in st_sensor_settings map in order to verify if
the driver needs to enable all sensor axis

and irq2
Define st_sensor_int_drdy structure in st_sensor_data_ready_irq in order
to contain irq line parameters of the device.
Moreover separate data-ready open-drain configuration parameters for INT1
and INT2 pins in st_sensor_data_ready_irq data structure.
That change will be used to properly support LIS3DHH accel sensor.

st_sensors_set_odr()
Do not try to configure sample frequency if the sensor do not export
odr register address in register map. That change will be used to
properly support LIS3DHH accel sensor.

channel type
IIO_DISTANCE is used for two purposes: for pedometers to record the
distance covered by a walker, and to measure the distance to an object
IIO_DISTANCE is in meters while IIO_PROXIMITY is a unitless measure
indirectly proportional to distance (higher value relates to a closer
object)

Subject: [PATCH 322/507] iio: hid-sensor-trigger: Don't touch sensors unless
user space requests
One of the user complained that on his system Thinkpad Yoga S1, with
commit f1664eaacec3 ("iio: hid-sensor-trigger: Fix the race with user
space powering up sensors") causes the system to resume immediately
on suspend (S3 operation). On this system the sensor hub is on USB
and is a wake up device from S3. So if any sensor sends data on
motion, the system will wake up. This can be a legitimate use case
to wake up device motion, but that needs proper user space support
to set right thresholds.
In fact the above commit didn't cause this regression, but any operation
which cause sensors to wake up would have caused the same issue. So if
user reads the raw sensor data, same issue occurs, with or without this
commit. Only difference is that the above commit by default will trigger
a power up and power down of sensors as part of runtime pm enable
(runtime enable will cause a runtime resume callback followed by
runtime_suspend callback). Previously user has to do some action on
sensors.
On investigation it was observed that the current driver correctly
changing the state of all sensors to power off but then also some sensor
will still send some data. Only option is to never power up any sensor.
Only good option is to:
- Using sysfs interface disable USB as a wakeup device (This will not
need any driver change)
Since some user don't care about sensors. So for those users this change
brings back old functionality. As long as they don't cause any operation
to power up sensors (like raw read or start iio-sensor-proxy service),
the sensors will not be to touched. This is done by delaying run time
enable till user space does some operation with sensors.

Subject: [PATCH 323/507] platform/chrome: Add cros_ec_accel_legacy driver
Add driver to support older EC firmware that only support deprecated
ec command. Rely on ACPI memory map register to access sensor
information.
Present same interface as the regular cros_ec sensor stack:
- one iio device per accelerometer
- use HTML5 axis definition
- use iio abi units
- accept calibration calls, but do nothing
Chrome can use the same code than regular cros_ec sensor stack to
calculate orientation and lid angle.

Subject: [PATCH 335/507] staging/ccree: Declare compiled out functions static
inline
Sparse was giving out a warning for symbols
'cc_set_ree_fips_status' and 'fips_handler'
that they were not declared and need to be
made static. This patch makes both the symbols
static inline, to remove the warnings.

The kbuild test robot reports the following:

odm_write_dig(dm, dig_tab->pause_dig_value[max_level]);
This condition is caused when a loop falls through. The fix is to pin
max_level to be >= 0.

Subject: [PATCH 349/507] rtl8188eu: Fix a possible sleep-in-atomic bug in
rtw_disassoc_cmd
The driver may sleep under a spinlock, and the function call path is:
rtw_set_802_11_bssid(acquire the spinlock)
rtw_disassoc_cmd
kzalloc(GFP_KERNEL) --> may sleep
To fix it, GFP_KERNEL is replaced with GFP_ATOMIC.
This bug is found by my static analysis tool and my code review.

Subject: [PATCH 350/507] rtl8188eu: Fix a possible sleep-in-atomic bug in
rtw_createbss_cmd
The driver may sleep under a spinlock, and the function call path is:
rtw_surveydone_event_callback(acquire the spinlock)
rtw_createbss_cmd
kzalloc(GFP_KERNEL) --> may sleep
To fix it, GFP_KERNEL is replaced with GFP_ATOMIC.
This bug is found by my static analysis tool and my code review.

Subject: [PATCH 355/507] staging: rtl8192e: Convert timers to use
timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

Subject: [PATCH 358/507] staging/comedi: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list pointer
to all timer callbacks, switch to using the new timer_setup() and
from_timer() to pass the timer pointer explicitly. Adds pointer back to
comedi device from private struct.

Subject: [PATCH 371/507] staging: pi433: rf69.c style fix - spaces
before/after
his patch fixes the following checkpatch.pl errors:
ERROR: space prohibited after that open parenthesis '('
ERROR: space prohibited before that ',' (ctx:WxV)
ERROR: space prohibited before that close parenthesis ')'
ERROR: space required after that ',' (ctx:VxV)
ERROR: space required before the open parenthesis '('
in rf69.c file as requested by TODO file.
Additionally some style warnings remain valid here and could be fixed by
another patch.

The solution is to add an extra parameter to the macro to
differentiate between buffer type and data type.

The cast to pointer types in kfree is not needed and can be dropped.
This was done using the following semantic patch by coccinelle,
except kfree((unsigned char*) pcmd->parmbuf) which was transformed by
hand because coccinelle didn't have enough type information.

Here the variable bips_processing is always supplied a bool value
while inside struct definition it is defined as an uint type.
Fix it by defining bips_processing a bool type.
Also a restore_iqk_rst = (pwrpriv->bips_processing == true) is same
as restore_iqk_rst = pwrpriv->bips_processing

Subject: [PATCH 383/507] staging: rtl8723bs: remove useless variable
rtw_AcceptAddbaReq
rtw_AcceptAddbaReq is a static variable, it is set once and never
modified. It is referenced only once, to assign its value to a member
of struct registry_priv.
Remove the variable, and move the meaningful part of the comment
near the declaration of the relevant field of struct registry_priv.

Subject: [PATCH 384/507] staging: rtl8723bs: remove implicit int->bool
conversions
Implicit type conversions are bad; they hinder readability of code and
have potential to cause bugs. Here the variable wait_ack is always
supplied a bool value while in function declarations it is defined as an
int type. Fix it by defining wait_ack a bool type in all usages.

Currently the rtl8723bs driver will print "nolinked power save enter"
and "nolinked power save leave" per minute if it's not connected to any
network.
These messages are meaningless and annoying to regular users.
Hide them when it's not debugging.

Subject: [PATCH 393/507] staging/fwserial: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. Also removes redundant initialization
of fw transaction timer, which already gets initialized per-transaction.

From 1f233190f15dc3aa2bf5a8ab84faf6b143e449fb Mon Sep 17 00:00:00 2001
From: Kees Cook <keescook@chromium.org>
Date: Mon, 16 Oct 2017 16:24:32 -0700
Subject: [PATCH 396/507] staging/wilc1000: Convert timers to use timer_setup()
As part of removing the timer_list.data field, this converts the wilc1000
driver to using from_timer and an explicit per-timer data field, since
there doesn't appear to be a way to sanely resolve vif from hif_drv.

Subject: [PATCH 402/507] vt6655: Fix a possible sleep-in-atomic bug in
vt6655_suspend
The driver may sleep under a spinlock, and the function call path is:
vt6655_suspend (acquire the spinlock)
pci_set_power_state
__pci_start_power_transition (drivers/pci/pci.c)
msleep --> may sleep
To fix it, pci_set_power_state is called without having a spinlock.
This bug is found by my static analysis tool and my code review.

Subject: [PATCH 407/507] staging: vboxvideo: Fix reporting invalid
suggested-offset-properties
The x and y hints receives from the host are unsigned 32 bit integers and
they get set to -1 (0xffffffff) when invalid. Before this commit the
vboxvideo driver was storing them in an u16 causing the -1 to be truncated
to 65535 which, once reported to userspace, was breaking gnome 3.26+
in Wayland mode.
This commit stores the host values in 32 bit variables, removing the
truncation and checks for -1, replacing it with 0 as -1 is not a valid
suggested-offset-property value. Likewise the properties are now
initialized to 0 instead of -1, since -1 is not a valid value.
This fixes gnome 3.26+ in Wayland mode not working with the vboxvideo
driver.

Make sure we only retry the operation while the portal is
busy and abort for all other error cases, otherwise we risk
entering an endless loop.

Subject: [PATCH 411/507] staging: fsl-dpaa2/eth: Check if notification rearm
is successful
In case dpaa2_io_service_rearm() fails with an error other then
EBUSY, it will do so silently; add a check for this and a warning
message, as a failure here means we're unable to receive any
more traffic on the current cpu.

Subject: [PATCH 413/507] staging: fsl-dpaa2/eth: Fix double DMA unmap
In case we fail to allocate a skb for a fragmented ingress
frame, the cleanup function will attempt to unmap again the
first frame fragment, which had already been unmapped during
early Rx processing.
Avoid this by freeing the first buffer immediately in case
we hit an error, leaving the cleanup function to free only
the subsequent buffers.

Subject: [PATCH 414/507] staging: fsl-dpaa2/eth: Use implicit clear of link
interrupt
dpni_get_irq_status() also looks at the input value of its
status parameter, and if not null it automatically clears
from pending state the bits that are set there.
Use this feature to avoid a separate MC command for clearing
the interrupt event bits after reading the status.

Subject: [PATCH 420/507] staging/irda-usb: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. This requires adding a pointer to
hold the timer's target URB, as there won't be a way to pass this in the
future.

Subject: [PATCH 425/507] staging: rtl8188eu: use pr_cont()
Using 'printk("\n")' is not preferred anymore as
printks without KERN_CONT are emitted on a new line and
KERN_CONT is required to continue lines so use pr_cont.

The sysfs attributes in_intensity0_thresh_period and
in_proximity0_thresh_period are currently directly created by the driver.
This patch migrates the creation of these sysfs attributes from the driver
to using the IIO core via iio_event_spec.

From: Brian Masney <masneyb@onstation.org>
Date: Thu, 19 Oct 2017 16:06:24 -0400
Subject: [PATCH 440/507] staging: iio: tsl2x7x: changed #defines to be aligned
on the same column
Some of the existing #defines have tabs between the name, and the value,
while others have spaces. The alignment of the values mostly has a
consistent layout, but there are some that don't. Change all of the
defines so that the name and value is separated by tabs and all of the
values start on the same column to increase code readability. This patch
also removes the unnecessary parentheses around the value of
TSL2X7X_MAX_TIMER_CNT.

Subject: [PATCH 443/507] staging: iio: tsl2x7x: correct alignment of
parenthesis
Correct error from checkpatch.pl to improve code readibility: Alignment
should match open parenthesis. This involved shortening the name of
tsl2x7x_als_gainadj and tsl2x7x_prx_gainadj to tsl2x7x_als_gain and
tsl2x7x_prx_gain respectively. This also required removing the
ch0lux and ch1lux local variables in order to get the line short
enough.

Subject: [PATCH 450/507] iio: dac: Add Texas Instruments 8/10/12-bit
2/4-channel DAC driver
The DACrrcS085 (rr = 08/10/12, c = 2/4) family of SPI DACs was
inherited by TI when they acquired National Semiconductor in 2011.
This driver was developed for and tested with the DAC082S085 built into
the Revolution Pi by KUNBUS, but should work with any of the other
chips as they share the same programming interface.
There is also a family of I2C DACs with just a single channel called
DACrr1C08x (rr = 08/10/12, x = 1/5). Their programming interface is
very similar and it should be possible to extend the driver for these
chips with moderate effort. Alternatively they could be integrated into
ad5446.c. (The AD5301/AD5311/AD5321 use different power-down modes but
otherwise appear to be comparable.)
Furthermore there is a family of 8-channel DACs called DACrr8S085
(rr = 08/10/12) as well as two 16-bit DACs called DAC161Sxxx
(xxx = 055/997). These are more complicated devices with support for
daisy-chaining and the ability to power down each channel separately.
They could either be handled by a separate driver or integrated into the
present driver with a larger effort.

Subject: [PATCH 451/507] iio: dac: ti-dac082s085: Read chip spec from device
table
The two properties unique to each supported chip, resolution and number
of channels, are currently gleaned from the chip's name.
E.g. dac102s085 is a dual channel 10-bit DAC.
^^^
This was deemed unmaintainable by the subsystem maintainer once the
driver is extended to support further chips, hence it was requested
to add an explicit table for chip-specific information and use an
enum to reference into it.
This adds 17 LoC without any immediate gain, so make the change in a
separate commit which can be reverted if we determine in 10 years that
it was unnecessary.

Subject: [PATCH 455/507] staging: greybus: spilib: fix use-after-free after
deregistration
Remove erroneous spi_master_put() after controller deregistration which
would access the already freed spi controller.
Note that spi_unregister_master() drops our only controller reference.

timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.
Additionally removes invalid NULL check, as pointed out by Dan Carpenter.

-if (pmlmepriv->cur_network.join_res != true) {

This is not equivalent as join_res is an int and can have values such

Subject: [PATCH 462/507] staging: rtl8188eu: Revert 4 commits breaking ARP
Commit 2ba8444c97b1 ("staging:r8188eu: move IV/ICV trimming into
decrypt() and also place it after rtl88eu_mon_recv_hook()") breaks ARP.
After this commit ssh-ing to a laptop with r8188eu wifi no longer works
if the machine connecting has never communicated with the laptop before.
This is 100% reproducable using "arp -d <ipv4> && ssh <ipv4>" to ssh to
a laptop with r8188eu wifi.
This commit reverts 4 commits in total:
1. Commit 79650ffde38e ("staging:r8188eu: trim IV/ICV fields in
validate_recv_data_frame()")
This commit depends on 2 of the other commits being reverted.
2. Commit 02b19b4c4920 ("staging:r8188eu: inline unprotect_frame() in
mon_recv_decrypted_recv()")
The inline code is wrong the un-inlined version contains:
if (skb->len < hdr_len + iv_len + icv_len)
return;
...
Where as the inline-ed code introduced by this commit does:
if (skb->len < hdr_len + iv_len + icv_len) {
...
Note the same check, but now to actually continue doing ... instead
of to not do it, so this commit is no good.
3. Commit d86e16da6a5d ("staging:r8188eu: use different mon_recv_decrypted()
inside rtl88eu_mon_recv_hook() and rtl88eu_mon_xmit_hook().")
This commit introduced a 1:1 copy of a function so that one of the
2 copies can be modified in the 2 commits we're already reverting.
4. Commit 2ba8444c97b1 ("staging:r8188eu: move IV/ICV trimming into
decrypt() and also place it after rtl88eu_mon_recv_hook()")
This is the commit actually breaking ARP.
Note this commit is a straight-forward squash of the revert of these
4 commits, without any changes.

Subject: [PATCH 463/507] staging: rtl8188eu: avoid a null dereference on
pmlmepriv
There is a check on pmlmepriv before dereferencing it when
vfree'ing pmlmepriv->free_bss_buf however the previous call
to rtw_free_mlme_priv_ie_data deferences pmlmepriv causing
a null pointer deference if it is null. Avoid this by also
calling rtw_free_mlme_priv_ie_data if the pointer is non-null.
Detected by CoverityScan, CID#1230262 ("Dereference before null check")

Subject: [PATCH 472/507] staging: VME: Remove PIO2 driver
The PIO2 device is (as far as I know) no longer manufactured. I no longer
have access to the device and this seems unlikely to change. The only
changes to this driver in a long time have been as a result of API changes
else where. Time to remove it...

From e8b1844a7e59fc35c086358021d9d42b4ce3ee22 Mon Sep 17 00:00:00 2001
From: Kees Cook <keescook@chromium.org>
Date: Tue, 24 Oct 2017 01:27:23 -0700
Subject: [PATCH 473/507] staging: rtl8723bs: Convert timers to use
timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. This performs some refactoring to
remove needless wrapper functions, and adds a pointer back to the desired
adapter.

Subject: [PATCH 476/507] staging: lustre: ldlm: remove unneeded 'err' arg to
ldlm_process_flock_lock()
This arg is used to return an error code, but the returned code is never
looked at. So there is no point returning it.

This is only ever set to LDLM_FL_WAIT_NOREPROC, so we can remove the arg
and discard any code that is only run when it doesn't have that value.

Subject: [PATCH 480/507] staging: lustre: ldlm: tidy list walking in
ldlm_flock()
Use list_for_each_entry variants to
avoid the explicit list_entry() calls.
This allows us to use list_for_each_entry_safe_from()
instread of adding a local list-walking macro.
Also improve some comments so that it is more obvious
that the locks are sorted per-owner and that we need
to find the insertion point.

'ownlocks', or pointing to the head of the list if ownlocks is NULL.
The current code then tests ownlocks and sets 'lock' to exactly the
value that it currently has.
So discard 'ownlocks'.
Also remove unnecessary initialization of 'lock'.

A caller should never care about a debugfs error return value, and it
should never abort its normal operation if something "odd" goes on. Fix
up the unisys init code to not care if the root debugfs directory for
the subsystem is created or not, as no place it is used will matter.

When configuring the Tx buffer layout, the software annotation size is
mentioned, and MC accounts for it when configuring the frame
tx_data_offset. No need to handle it in the driver as well.
This results in 64B less memory allocated per frame.

Subject: [PATCH 487/507] staging: fsl-dpaa2/eth: Change RX buffer alignment
The WRIOP hardware block v1.0.0 (found on LS2080A board)
requires data in RX buffers to be aligned to 256B, but
newer revisions (e.g. on LS2088A, LS1088A) only require
64B alignment.
Check WRIOP version and decide at runtime which alignment
requirement to configure for ingress buffers.

Subject: [PATCH 488/507] staging: fsl-dpaa2/eth: Extra headroom in RX buffers
The needed headroom that we ask the stack to reserve for us in TX
skbs is larger than the headroom available in RX frames, which
leads to skb reallocations in forwarding scenarios involving two
DPNI interfaces.
Configure the hardware to reserve some extra space in the RX
frame headroom to avoid this situation. The value is chosen based
on the Tx frame data offset, the Rx buffer alignment value and the
netdevice required headroom.
The network stack will take care to reserve space for HH_DATA_MOD when
building the skb, so there's no need to account for it in the netdevice
needed headroom.

Subject: [PATCH 489/507] staging: greybus/loopback: use ktime_get() for time
intervals
This driver is the only one using the deprecated timeval_to_ns()
helper. Changing it from do_gettimeofday() to ktime_get() makes
the code more efficient, more robust against concurrent
settimeofday(), more accurate and lets us get rid of that helper
in the future.

Subject: [PATCH 490/507] staging: greybus: loopback: Hold per-connection mutex
across operations
Commit d9fb3754ecf8 ("greybus: loopback: Relax locking during loopback
operations") changes the holding of the per-connection mutex to be less
restrictive because at the time of that commit per-connection mutexes were
encapsulated by a per-driver level gb_dev.mutex.
Commit 8e1d6c336d74 ("greybus: loopback: drop bus aggregate calculation")
on the other hand subtracts the driver level gb_dev.mutex but neglects to
move the mutex back to the place it was prior to commit d9fb3754ecf8
("greybus: loopback: Relax locking during loopback operations"), as a
result several members of the per connection struct gb_loopback are racy.
The solution is restoring the old location of mutex_unlock(&gb->mutex) as
it was in commit d9fb3754ecf8 ("greybus: loopback: Relax locking during
loopback operations").

Commit 12927835d211 ("greybus: loopback: Add asynchronous bi-directional
support") does what it says on the tin - namely, adds support for
asynchronous bi-directional loopback operations.
What it neglects to do though is increment the per-connection
gb->iteration_count on an asynchronous operation error. This patch fixes
that omission.

Subject: [PATCH 492/507] staging: greybus: operation: add private data with
get/set accessors
Asynchronous operation completion handler's lives are made easier if there
is a generic pointer that can store private data associated with the
operation. This patch adds a pointer field to struct gb_operation and
get/set methods to access that pointer.

Subject: [PATCH 493/507] staging: greybus: loopback: convert loopback to use
generic async operations
Loopback has its own internal method for tracking and timing out
asynchronous operations however previous patches make it possible to use
functionality provided by operation.c to do this instead. Using the code in
operation.c means we can completely subtract the timer, the work-queue, the
kref and the cringe-worthy 'pending' flag. The completion callback
triggered by operation.c will provide an authoritative result code -
including -ETIMEDOUT for asynchronous operations.

Subject: [PATCH 495/507] staging: fbtft: fb_ssd1331: fix mirrored display
When the row scan order is reversed (the default) we also need to
reverse the column scan order. This was not done previously, resulting
in a mirrored display.
Also add support for 180 degree display rotation, in which case simply
disable reversed row and column scan order.
Tested on an Adafruit 0.96" mini Color OLED display.

Commit 46949b48568b ("staging: wilc1000: New cfg packet
format in handle_set_wfi_drv_handler") updated the frame
format sent from host to the firmware. The code to update
the bssid offset in the new frame was part of a second
patch in the series which did not make it in and thus
causes connection problems after associating to an AP.
This fix adds the proper offset of the bssid value in the
Tx queue buffer to fix the connection issues.

parameter that was not actually used. Simplify the whole thing
by dropping it and rename the macro for better readability.

From 7f5ce9dddbab6c76f7b7aa040c4c0bfb00530047 Mon Sep 17 00:00:00 2001
From: Gilad Ben-Yossef <gilad@benyossef.com>
Date: Mon, 6 Nov 2017 06:55:52 +0000
Subject: [PATCH 504/507] staging: ccree: simplify ioread/iowrite
Registers ioread/iowrite operations were done via macros,
sometime using a "magical" implicit parameter.
Replace all register access with simple inline macros.

Subject: [PATCH 505/507] staging: greybus: add SPDX identifiers to all greybus
driver files
It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/staging/greybus files files with the correct SPDX
license identifier based on the license text in the file itself. The
SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

From 863dbc52e7f0e5acd7b4883f3933543a81c474c7 Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: Tue, 7 Nov 2017 14:58:42 +0100
Subject: [PATCH 506/507] staging: greybus: Remove redundant license text
Now that the SPDX tag is in all greybus files, that identifies the
license in a specific and legally-defined manner. So the extra GPL text
wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

From c14dd9d5f8beda9d8c621683b4e7d6cb5cd3cda7 Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: Tue, 7 Nov 2017 14:58:46 +0100
Subject: [PATCH 507/507] staging: lustre: add SPDX identifiers to all lustre
files
It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/staging/lustre files files with the correct SPDX
license identifier based on the license text in the file itself. The
SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.
