From 14e7157afb055248ed34901fcd6fbf54201cfea1 Mon Sep 17 00:00:00 2001 From: Liang He Date: Tue, 19 Jul 2022 14:54:47 +0800 Subject: [PATCH] drm/bridge: tc358767: Add of_node_put() when breaking out of loop In tc_probe_bridge_endpoint(), we should call of_node_put() when breaking out of the for_each_endpoint_of_node() which will automatically increase and decrease the refcount.
