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 patches 1/2 and 2/2 in this patchset try to handle all the review comments received on the following UVC gadget related patches: [PATCH V3 3/5] usb: gadget/uvc: Port UVC webcam gadget to use videobuf2 framework [PATCH V3 5/5] usb: gadget/uvc: Add support for 'get_unmapped_area' for MMUless architectures which can be viewed here: [1] http://comments.gmane.org/gmane.linux.usb.general/77772 [2] http://www.spinics.net/lists/linux-usb/msg77400.html The rest of the patches in the V3 patchset have already been accepted into Laurent's git tree. 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 patch. Changes since V3: - Addresses the review comments received on V3 of this patchset from Laurent and Michael Grzeschik. - 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.
