2011-03-22[media] uvcvideo: Fix uvc_fixup_video_ctrl() format searchStephan Lachowsky1-5/+9
The scheme used to index format in uvc_fixup_video_ctrl() is not robust: format index is based on descriptor ordering, which does not necessarily match bFormatIndex ordering. Searching for first matching format will prevent uvc_fixup_video_ctrl() from using the wrong format/frame to make adjustments.

2011-03-22[media] af9015: enhance RCIan Armstrong2-11/+29
Patch from Ian Armstrong. I've encountered a couple of problems with the current af9015 driver as supplied with the 2.6.37 kernel, that the attached patch appears to fix. (I've generated this patch against the current v4l-dvb git). Some key-presses are lost. A key-press is only generated upon 'valid' data (buf[14] == (u8) ~buf[15]), but the buffer is wiped before this check. Sometimes the 15th byte has not been set at the time of read, so the data isn't valid & ignored. On the next poll the 15th byte has been set, but the rest of the data was wiped previously, so the data is still invalid & the key is lost. Weird repeat error, where an old key press is sometimes repeated in error. ie. button sequence '1 (pause) 2 (pause) 3 (pause) 4' generates output like '1 (pause) 2 (pause) 23 (pause) 4'. The current driver zeroes the data for the key pushed, but sometimes this data is already zero but with other bytes set suggesting a repeat code. This results in the last key being incorrectly repeated. This patch attempts to reduce the risk of a missed key-press & also stop the random repeat of an old key-press when a new key is pressed.

Rework the locking in m2m driver to assure proper operation on SMP systems. When job_abort or stop_streaming was called to immediately shutdown a memory-to-memory transaction video buffers scheduled for processing were never returned to vb2 and v4l2_m2m_job_finish was not called which led to hanging. Correct this and also return the unprocessed buffers to vb2 marking them as erroneous, in case the end of frame interrupt do not occur.

In some cases fimc H/W did not stop although there were no output buffers available. So the capture deactivation interrupt routine is modified and the state of ST_CAPT_RUN is cleared only in the LAST-IRQ call. After LAST-IRQ is generated, H/W pointer will be skipped by 1 frame. (reference by user manual) So, S/W pointer should be increased too.
