From: Nishka Dasgupta <nishkadg.linux@xxxxxxxxx> commit 89fea04c85e85f21ef4937611055abce82330d48 upstream. Each iteration of for_each_child_of_node puts the previous node, but in the case of a break from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the break. Issue found with Coccinelle.
