[PATCH] drm/sun4i: tcon: Fix refcount leak bug in sun4i_tcon_of_get_id_from_port()

[Liang He]

We should call of_node_put() for the reference returned by
of_graph_get_remote_endpoint() when it is not used anymore.

Fixes: e8d5bbf7f4c4 ("drm/sun4i: tcon: get TCON ID and matching engine with 
remote endpoint ID")
