Subject: [PATCH v1 09/12] drm/rcar-du: lvds: Use drm_bridge_funcs.atomic_check
Date: Sun, 17 Jul 2022 19:57:58 +0200	[thread overview]
Message-ID: <20220717175801.78668-2-sam@ravnborg.org> (raw)
In-Reply-To: <20220717175801.78668-1-sam@ravnborg.org>

Replace the deprecated drm_bridge_funcs.mode_fixup() with
drm_bridge_funcs.atomic_check().
The driver implements the state operations, so no other changes
are required for the replacement.
