[PATCH 5.15 189/913] regulator: qcom_smd: fix for_each_child.cocci warnings

[Greg Kroah-Hartman]

From: kernel test robot <lkp@xxxxxxxxx>

[ Upstream commit 6390d42c21efff0b4c10956a38e341f4e84ecd3d ]

drivers/regulator/qcom_smd-regulator.c:1318:1-33: WARNING: Function "for_each_available_child_of_node" should have of_node_put() before return around line 1321.

Semantic patch information:
 False positives can be due to function calls within the for_each
 loop that may encapsulate an of_node_put.

Generated by: scripts/coccinelle/iterators/for_each_child.cocci

Fixes: 14e2976fbabd ("regulator: qcom_smd: Align probe function with rpmh-regulator")
