Subject: [PATCH 07/13] media: rockchip: rga: use clamp() to clamp size to limits
Date: Thu, 14 Sep 2023 14:40:39 +0200	[thread overview]
Message-ID: <20230914-rockchip-rga-multiplanar-v1-7-abfd77260ae3@pengutronix.de> (raw)
In-Reply-To: <20230914-rockchip-rga-multiplanar-v1-0-abfd77260ae3@pengutronix.de>

The try_fmt should limit the width and height to the know limits of the
RGA. Use the clamp() helper instead of open coding the clamping.
