Subject: [PATCH] drm/bridge: lvds-codec: Use dev_err_probe for error handling
Date: Tue, 20 Oct 2020 10:36:55 +0100	[thread overview]
Message-ID: <20201020093655.3584-1-biju.das.jz@bp.renesas.com> (raw)

dev_err_probe function simplifies error handling. So use the same in probe
function wherever possible.
