Subject: [PATCH] soc: qcom: apr: Add of_node_put() before return
Git-commit: 72f1aa6205d84337b90b065f602a8fe190821781
Patch-mainline: v5.16-rc1
References: git-fixes stable-5.14.19

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.
