drm/bridge: tc358767: Add of_node_put() when breaking out of loop
[ Upstream commit 14e7157afb055248ed34901fcd6fbf54201cfea1 ]
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.
