From 65c04add090f029abe8255f28448d9a12dd27828 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 25 Feb 2020 00:56:45 +0200 Subject: [PATCH] drm/bridge: lvds-codec: Add to_lvds_codec() function Factor out the manual container_of() uses to a common to_lvds_codec() macro to shorten lines (and provide better type safety, although that won't matter much in this case).
