From 78e420408d12eddd0e72613fc717f7994736ea9a Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Tue, 23 Jul 2019 16:13:07 +0530 Subject: net: dsa: mv88e6xxx: chip: 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. Issue found with Coccinelle. Signed-off-by: Nishka Dasgupta Signed-off-by: David S.
