Subject: [media] uvcvideo: Remove buffers from the queues when freeing
X-Git-Tag: v3.0-rc7~46^2~14
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8ca2c80b170c47eeb55f0c2a0f2b8edf85f35d49;p=pandora-kernel.git

[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
