From 2ff110bbe98e2beeb6488021fb650b1afc736263 Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Thu, 15 Aug 2019 11:37:18 +0530 Subject: pinctrl: meson: meson: 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.
