This patchset tries to enhance the UVC webcam gadget driver and is based on Laurent's git tree available here (head uvc-gadget): git://linuxtv.org/pinchartl/uvcvideo.git Note that to ease review and integration of these patches, I have rebased them on Laurent's repo and all the relevant patches after review can be pushed in Felipe's repo in one go. The patch 1/2 in this patchset tries to handle all the review comments received on the V4 of the following UVC gadget related patch: [PATCH V4 1/2] usb: gadget/uvc: Port UVC webcam gadget to use videobuf2 framework which can be viewed here: [1] http://www.mail-archive.com/linux-usb@xxxxxxxxxxxxxxx/msg17810.html The patch 2/2 in this patchset has already received an Acked-By from Laurent. I have tested this patchset on a super-speed compliant USB device controller (DWC3), with the VIVI capture device acting as a dummy source of video data and I also have modified the 'uvc-gadget' application written by Laurent (original application available here: http://git.ideasonboard.org/uvc-gadget.git) for testing the complete flow from V4L2 to UVC domain and vice versa. I will send a patch for the modified 'uvc-gadget' application in a separate mail thread. Changes since V4: - Addresses the review comments received on V4 of this patchset from Laurent. - The changes suggested by Laurent and Alan to remove WARN_ON messages from the UDC controller drivers in case the gadget tries to dequeue a USB request which was never queued to the UDC controller, will be floated as a separate patch.
