Subject: [PATCH] regulator: qcom_smd: fix for_each_child.cocci warnings
Date: Sat, 15 Jan 2022 12:11:38 +0100 (CET) [thread overview]
Message-ID: <alpine.DEB.2.22.394.2201151210170.3051@hadrien> (raw)
From: kernel test robot <lkp@intel.com>
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")
