"lnk" is used as "port0", and it will be used to get "port1" by of_get_next_child(ports, lnk). It will call of_node_put() inside. This function is calling of_node_get() to make up for it, but it doesn't call paired of_node_put(port0) when it quit function. This of_node_get() itself is not needed, let's remove it.
