Subject: [PATCH 01/17] drm/cirrus: Compute blit destination offset in single location
Date: Wed, 15 Feb 2023 17:15:01 +0100	[thread overview]
Message-ID: <20230215161517.5113-2-tzimmermann@suse.de> (raw)
In-Reply-To: <20230215161517.5113-1-tzimmermann@suse.de>

The calculation for the scanout-buffer blit offset is independent
from the color format. In the one case where the current code uses
fb->pitches[0] instead of cirrus->pitch, their values are identical.
Hence merge all into a single line.
