Subject: [PATCH 09/13] media: rockchip: rga: add local variable for pix_format
Date: Thu, 14 Sep 2023 14:40:41 +0200	[thread overview]
Message-ID: <20230914-rockchip-rga-multiplanar-v1-9-abfd77260ae3@pengutronix.de> (raw)
In-Reply-To: <20230914-rockchip-rga-multiplanar-v1-0-abfd77260ae3@pengutronix.de>

The local variable allows to simplify the accessed to the format and
makes it easier to change the type of the format.
