From db2a17320a25a63b46ddb081a306af9ded1b906e Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Sun, 4 Aug 2019 21:50:23 +0530 Subject: regulator: core: 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 in two places. Issue found with Coccinelle.
