2011-07-13uvcvideo: Remove buffers from the queues when freeingSjoerd Simons
commit 8ca2c80b170c47eeb55f0c2a0f2b8edf85f35d49 upstream. When freeing memory for the video buffers also remove them from the irq & main queues. This fixes an oops when doing the following: open ("/dev/video", ..)

2011-03-27uvcvideo: Fix uvc_fixup_video_ctrl() format searchStephan Lachowsky
commit 38a66824d96de8aeeb915e6f46f0d3fe55828eb1 upstream. 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.

2009-06-16V4L/DVB (11837): uvcvideo: Start status polling on device openLaurent Pinchart
Most UVC camera include an interrupt endpoint to report control value changes, video streaming errors and camera button events. The USB controller continuously polls the interrupt endpoint to retrieve such events. This prevents the device from being auto-suspended, and thus consumes power. Reporting video streaming errors don't make sense when the V4L2 device is closed. Control value changes are probably useless as well if nobody listens to the events, although caching will probably have to be completely disabled then. No polling is thus be required when /dev/videoX is not opened. To enable auto-suspend and save power do not poll the interrupt endpoint until the device is open. We lose the ability to detect button events if no application is using the camera. http://bugzilla.kernel.org/show_bug.cgi?id=11948 Signed-off-by: Laurent Pinchart <laurent.pinchart@skynet.be> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
