[PATCHv2 00/19] media: clean up unnecessary vb2_queue_release calls

[Hans Verkuil <hverkuil+cisco@kernel.org>]

Many drivers call vb2_queue_release() unnecessarily. There is normally no
reason for drivers to call this function directly, instead call
(_)vb2_fop_release(), vb2_video_unregister_device() or
v4l2_m2m_ctx_release().

This series removes the vb2_queue_release() calls from most drivers.

There are still a few old drivers that call it, but let's get the
majority fixed.

Regards,

	Hans

Changes since v1:
- improve commit logs
- ensure media_entity_cleanup comes after vb2_video_unregister_device
- fix a few compiler warnings for unused vq variables
