Subject: [PATCH] drm: bridge: thc63lvd1024: Switch to use of_graph_get_remote_node()
Date: Sun, 17 Mar 2024 01:28:00 +0800
Message-Id: <20240316172800.1168390-1-sui.jingfeng@linux.dev>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

To reduce boilerplate, use of_graph_get_remote_node() helper instead of
the hand-rolling code.
