Subject: [RFC PATCH v4 10/12] media: imx219: use a local v4l2_subdev to simplify reading
Date: Thu, 3 Feb 2022 18:50:07 +0100 [thread overview]
Message-ID: <20220203175009.558868-11-jeanmichel.hautbois@ideasonboard.com> (raw)
In-Reply-To: <20220203175009.558868-1-jeanmichel.hautbois@ideasonboard.com>
There is no need to dereference the imx219 structure. Use a local
v4l2_subdev instead.
