From cf36dd2f7793e8b2723e3eca518fff1be840a297 Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Tue, 16 Jul 2019 11:25:04 +0530 Subject: [PATCH] net: ethernet: mediatek: mtk_eth_soc: Add of_node_put() before goto Each iteration of for_each_child_of_node puts the previous node, but in the case of a goto from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the goto. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta Signed-off-by: David S.
