From beae796d66165b40d80b743ae301a29c312d7320 Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Tue, 23 Jul 2019 16:21:08 +0530 Subject: phy: marvell: phy-mvebu-a3700-comphy: Add of_node_put() before return Each iteration of for_each_available_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 in two places. Issue found with Coccinelle.
