The local variable np in function rcar_sysc_pd_init takes the return value of of_find_matching_node_and_match, which gets a node but does not put it. If np is not put before the function returns, it may cause a memory leak. Hence, remove the return statement that does not immediately follow a putting of np. Replace it with a goto pointing to a pre-existing label that first puts np and then returns the required value. Issue found with Coccinelle.
