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 Acked-by: Laurent Pinchart Cc: stable@kernel.org Signed-off-by: Mauro Carvalho Chehab --- diff --git a/drivers/media/video/uvc/uvc_queue.c b/drivers/media/video/uvc/uvc_queue.c index 109a06384a8f..f90ce9fce539 100644 --- a/drivers/media/video/uvc/uvc_queue.c +++ b/drivers/media/video/uvc/uvc_queue.c @@ -104,6 +104,8 @@ static int __uvc_free_buffers(struct uvc_video_queue *queue) } if (queue->count) { + uvc_queue_cancel(queue, 0); + INIT_LIST_HEAD(&queue->mainqueue); vfree(queue->mem); queue->count = 0; }
