[ 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")
