[PATCH 5.10 451/575] soc: qcom: apr: Add of_node_put() before return

[Greg Kroah-Hartman]

From: Wan Jiabing <wanjiabing@xxxxxxxx>

[ Upstream commit 72f1aa6205d84337b90b065f602a8fe190821781 ]

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.

Fixes: 834735662602 ("soc: qcom: apr: Add avs/audio tracking functionality")
