Subject: [PATCH] soc: qcom: apr: Add of_node_put() before return
Date: Thu, 14 Oct 2021 04:30:17 -0400	[thread overview]
Message-ID: <20211014083017.19714-1-wanjiabing@vivo.com> (raw)

Fix following coccicheck warning:

./drivers/soc/qcom/apr.c:485:1-23: 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.
