net: dsa: sja1105: sja1105_main: Add of_node_put()
Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta <nishkadg.linux@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
