Message-ID: <20200713113048.1150542-1-hverkuil-cisco@xs4all.nl> (raw)

This series supersedes this patch:

https://patchwork.linuxtv.org/project/linux-media/patch/7e7e9841-7f3a-468b-01c8-5921e5c14df8@xs4all.nl/

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.

Regards,

	Hans
