This series supersedes this patch: https://patchwork.linuxtv.org/project/linux-media/patch/7e7e9841-7f3a-468b-01c8-5921e5c14df8@xxxxxxxxx/ This series checks drivers that use vb2_queue_release() incorrectly and fixes them, and calls vb2_video_unregister_device() as well if the driver set vdev->queue. There are a lot more drivers that set vdev->queue and can probably benefit from using vb2_video_unregister_device(), but that's something for a future series. The main focus of this series is to check for incorrect use of vb2_queue_release(). Changes since v2: add patches 2-7.
