This function gets a device_node reference via of_graph_get_remote_port_parent() and stores it in encoder_node, but never puts that reference. Add it. There used to be a of_node_put(encoder_node) but it has been removed by mistake during a rework in commit3ea66a794f("drm/arc: Inline arcpgu_drm_hdmi_init").
