Subject: [PATCH] media: cx231xx: controls are from another device, mark this
Date: Wed, 17 Jan 2024 12:44:03 +0100	[thread overview]
Message-ID: <4abc72aa-8768-4b1c-a940-811c7a918b1d@xs4all.nl> (raw)

The last argument of v4l2_ctrl_add_handler() indicates whether the controls
you add are from a control handler owned by another driver (true) or from the
same driver (false). In this case the last argument was incorrectly set to
false. The controls come from the cx25840 subdev.
