Subject: [PATCH AUTOSEL 5.10 053/217] drm/bridge: lvds-codec: Use dev_err_probe for error handling
Date: Tue, 22 Dec 2020 21:13:42 -0500	[thread overview]
Message-ID: <20201223021626.2790791-53-sashal@kernel.org> (raw)
In-Reply-To: <20201223021626.2790791-1-sashal@kernel.org>

From: Biju Das <biju.das.jz@bp.renesas.com>

[ Upstream commit 4178bd5a3c57e107b3df5e17de6dc60cb3890647 ]

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