[media] uvcvideo: Remove buffers from the queues when freeing
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", ..) VIDIOC_REQBUFS VIDIOC_QBUF VIDIOC_REQBUFS close () As the second VIDIOC_REQBUFS will cause the list entries of the buffers to be cleared while they still hang around on the main and irc queues Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: stable@kernel.org Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
