Subject: [PATCH 00/19] media: clean up unnecessary vb2_queue_release calls
Date: Fri, 17 Jul 2026 10:19:23 +0200	[thread overview]
Message-ID: <cover.1784276382.git.hverkuil+cisco@kernel.org> (raw)

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
