Subject: [PATCH] hwmon: (tmp421) Add of_node_put() before return
Date: Mon, 18 Oct 2021 08:15:37 -0400 [thread overview]
Message-ID: <20211018121538.16482-1-wanjiabing@vivo.com> (raw)
Fix following coccicheck warning:
./drivers/hwmon/tmp421.c:416:1-23: WARNING: Function
for_each_child_of_node should have of_node_put() before return.
Early exits from for_each_child_of_node should decrement the
node reference counter.
