Subject: [PATCH v1 2/6] media: imx: imx7-media-csi: Simplify imx7_csi_video_init_format()
Date: Fri, 27 Jan 2023 04:27:11 +0200	[thread overview]
Message-ID: <20230127022715.27234-3-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20230127022715.27234-1-laurent.pinchart@ideasonboard.com>

The imx7_csi_video_init_format() function instantiates a
v4l2_subdev_format on the stack, to only use the .format field of that
structure. Replace it with a v4l2_mbus_framefmt instance.
