From 7fb8cc3eb6716dcb14d00be9e59562fbf6259595 Mon Sep 17 00:00:00 2001 From: ZhangPeng Date: Fri, 25 Nov 2022 07:01:56 +0000 Subject: [PATCH] pinctrl: pinconf-generic: add missing of_node_put() [ Upstream commit 5ead93289815a075d43c415e35c8beafafb801c9 ] of_node_put() needs to be called when jumping out of the loop, since for_each_available_child_of_node() will increase the refcount of node.
