From 9f7546570bcb20debfaa97bcf720fa0fcb8fc05a Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Sat, 6 Jul 2019 18:51:30 +0530 Subject: [PATCH] hwmon: (ina3221) Add of_node_put() before return 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.
