From 7f028caadf6c37580d0f59c6c094ed09afc04062 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski krzk@kernel.org Date: Mon, 5 Aug 2019 18:27:09 +0200 Subject: [PATCH] pinctrl: samsung: Fix device node refcount leaks in S3C64xx wakeup controller init
In s3c64xx_eint_eint0_init() the for_each_child_of_node() loop is used with a break to find a matching child node. Although each iteration of for_each_child_of_node puts the previous node, but early exit from loop misses it. This leads to leak of device node.
