This is the capacity in percentage, relative to design capacity. Specifically, it is present in Apple Magic Mouse 2. In contrast, usage 00850064 is also the capacity in percentage, but is relative to full capacity. It is not mapped here because I don't have such device. Signed-off-by:

It is observed that the Magic Mouse 2 would not enter multi-touch mode unless the mouse is connected before loading the module. It seems to be a quirk specific to Magic Mouse 2 Retrying after 500ms fixes the problem for me. The delay can't be reduced much further --- 300ms didn't work for me. Retrying immediately after receiving an event didn't work either. Signed-off-by:

It is observed that, with 3 button emulation, when middle button is clicked, either the left button or right button is clicked as well. It is caused by hidinput "correctly" acting on the event, oblivious to the 3 button emulation. As raw_event has taken care of everything, no further processing is needed. However, the only way to stop at raw_event is to return an error (negative) value. Therefore, the processing is stopped at event instead. [jkosina@suse.cz: fix comment style] Signed-off-by:

The Thinkpad X1 Tablet Thin keyboard's HID interface for the media-keys and other special functions, is quite similar to the Thinkpad 10 ultrabook keyboard's mouse/media-keys HID interface. The only difference is that it needs a bit different key mappings. Add support for the mute-LED and the non-standard media-keys on this keyboard by re-using the tp10_ultrabook_kbd code combined with a new lenovo_input_mapping_x1_tab_kbd() function. Co-authored-by:

Instead of looking for a hdev with a type of HID_TYPE_USBMOUSE find the interface for the mute/mic-mute/fn-lock LEDs by checking for the output-report which is used to set them. This is a preparation patch for adding support for the LEDs on the X1 tablet thin keyboard which uses the same output-report, but has a separate (third) USB interface for the touchpad/mouse functionality.

The mute and mic-mute LEDs should be automatically turned on/off based on the audio-card's mixer settings. Add the standardized default-trigger names for this, so that the alsa code can turn the LEDs on/off as appropriate (on supported audio cards). This brings the mute/mic-mute LED support inline with the thinkpad_acpi support for the same LEDs in keyboards directly connected to the laptop's embedded-controller. Reviewed-by:

Mapping the mic-mute button to KEY_MICMUTE is technically correct but KEY_MICMUTE translates to a scancode of 256 (248 + 8) under X, which does not fit in 8 bits, so it does not work. Because of this userspace is expecting KEY_F20 instead, theoretically KEY_MICMUTE should work under Wayland but even there it does not work, because the desktop-environment is listening only for KEY_F20 and not for KEY_MICMUTE.

The led_classdev already contains a cached value of the last set brightness, the brightness_get callback is only meant for LED drivers which can read back the actual / current brightness from the hardware. Since lenovo_led_brightness_get() just returns the last set value it does not add any functionality, so we can just remove it. Reviewed-by:

The HID lenovo probe function only attaches drvdata to one of the USB interfaces, but lenovo_event() will get called for all USB interfaces to which hid-lenovo is bound. This allows a malicious device to fake being a device handled by hid-lenovo, which generates events for which lenovo_event() has special handling (and thus dereferences hid_get_drvdata()) on another interface triggering a NULL pointer exception. Add a check for hid_get_drvdata() returning NULL, avoiding this possible NULL pointer exception. Fixes: bc04b37e ("HID: lenovo: Add ThinkPad 10 Ultrabook Keyboard support") Reviewed-by:

Fix the following issues with lenovo_led_set_tp10ubkbd() error handling: 1. On success hid_hw_raw_request() returns the number of bytes sent. So we should check for (ret != 3) rather then for (ret != 0). 2. Actually propagate errors to the caller. 3. Since the LEDs are part of an USB keyboard-dock the mute LEDs can go away at any time. Don't log an error when ret == -ENODEV and set the LED_HW_PLUGGABLE flag to avoid errors getting logged when the USB gets disconnected.

The lenovo_led_brightness_set function may sleep, so we should have the the led_class_dev's brightness_set_blocking callback point to it, rather then the regular brightness_set callback. When toggled through sysfs this is not a problem, but the brightness_set callback may be called from atomic context when using LED-triggers.

Being integrated into an USB keyboard-dock the mute LED can go away at any time, leading to the following errors: [ 918.667671] elan 0003:04F3:0755.0002: Failed to set mute led brightness: -19 [ 918.667737] leds elan:red:mute: Setting an LED's brightness failed (-19) Fix this by making the following changes: 1.

Add support for the legacy keyboard (KBD/TC=0x08) HID transport layer of the Surface System Aggregator Module (SSAM) to the Surface HID driver. On Surface Laptops 1 and 2, this interface is used to connect the integrated keyboard. Note that this subsystem interface essentially provides a limited HID transport layer. In contrast to the generic HID interface (TC=0x15) used on newer Surface models, this interface only allows (as far as we know) for a single device to be connected and is otherwise severely limited in terms of support for feature- and output-reports. Specifically, only caps-lock-LED output-reports and a single read-only feature-report are supported. Signed-off-by:

Add a HID transport driver to support integrated HID devices on newer Microsoft Surface models (specifically 7th-generation, i.e. Surface Laptop 3, Surface Book 3, and later). On those models, the internal keyboard and touchpad (as well as some other HID devices with currently unknown function) are connected via the generic HID subsystem (TC=0x15) of the Surface System Aggregator Module (SSAM). This subsystem provides a generic HID transport layer, support for which is implemented by this driver. Co-developed-by:

Plantronics Blackwire 3220 Series (047f:c056) sends HID reports twice for each volume key press. This patch adds a quirk to hid-plantronics for this product ID, which will ignore the second volume key press if it happens within 5 ms from the last one that was handled. The patch was tested on the mentioned model only, it shouldn't affect other models, however, this quirk might be needed for them too. Auto-repeat (when a key is held pressed) is not affected, because the rate is about 3 times per second, which is far less frequent than once in 5 ms.
