From f17d2f54d36dd316bcff4e619a1a349f04214a83 Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Sun, 4 Aug 2019 20:57:45 +0530 Subject: pinctrl: falcon: Add of_node_put() before return Each iteration of for_each_compatible_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.
