Subject: [PATCH 2/7] drm/logicvc: Fix preferred fbdev cpp
Date: Wed, 16 Nov 2022 17:09:12 +0100	[thread overview]
Message-ID: <20221116160917.26342-3-tzimmermann@suse.de> (raw)
In-Reply-To: <20221116160917.26342-1-tzimmermann@suse.de>

Logicvc can have different values for the preferred color depth. Set
the fbdev bpp value depending on the runtime value.
