It would then unconditionally try return a flush completion via qib_send_complete() for an invalid wqe, or worse a valid one that is not queued. The panic results when the completion code tries to maintain an MR reference count for a NULL MR. This fix modifies logic to only send one completion per qib_make_rc_req() call and changing the completion status from IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress. The outer loop will call as many times as necessary to flush the queue. Reviewed-by:Ram Vepa <ram.vepa@qlogic.com> Signed-off-by:

The current driver never does DMA unmapping on these buffers. Fix that by adding DMA unmapping to the task cleanup callback, and DMA mapping to the task init function (drop the headers_initialized micro-optimization). Signed-off-by:

The driver counted on the transactional nature of iSCSI login/text flows and used the same buffer for both the request and the response. We also went further and did DMA mapping only once, with DMA_FROM_DEVICE, which violates the DMA mapping API. Fix that by using different buffers, one for requests and one for responses, and use the correct DMA mapping direction for each. Signed-off-by:

This is essentially a stripped down version of the W83627DHG. Noticeable difference is that it is still powered with +5V, as older models, even though the ADC resolution is 8 mV as newer models have. Thanks to Ulf Bruman (Saab Group) for doing all the testing. Signed-off-by:

The probe function has grown pretty large, I think it's time for some cleanups, starting with these two simple ones: * Move temp3/in6 check for the W83667HG later in the function, where it is done for all other chip types. * Move temperature register setting to a separate function, to avoid code duplication.

With some configuration option combinations, we get the following warnings: drivers/hwmon/lm90.c: In function 'lm90_detect': drivers/hwmon/lm90.c:1114: warning: 'chip_id' may be used uninitialized in this function drivers/hwmon/lm90.c:1114: warning: 'reg_config1' may be used uninitialized in this function drivers/hwmon/lm90.c:1114: warning: 'reg_convrate' may be used uninitialized in this function drivers/hwmon/lm90.c:1187: warning: 'reg_emerg2' may be used uninitialized in this function drivers/hwmon/lm90.c:1187: warning: 'reg_status2' may be used uninitialized in this function We can solve these easily by reading the register values first and checking for errors later. These errors should be very rare, even in the case of failed detection, so this change has no impact on performance. And this makes checkpatch.pl happier. Reported-by:

If "i" is 2 then when we call cx25821_video_mux() we'd end up going past the end of the cx25821_boards[dev->board]->input[]. The INPUT() macro obfuscates what's going on in that function so it's a bit hard to follow. And as Mauro points out the hard coded 2 is not very helpful. Signed-off-by:

The Kconfig symbol RADIO_TEA5764_XTAL is unused. The code does use a RADIO_TEA5764_XTAL macro, but does that rather peculiar. But there seems to be a way to keep both. (The easiest way out would be to rip out both the Kconfig symbol and the macro.) Note there's also a module parameter 'use_xtal' to influence all this. Signed-off-by:
