From afc954fd223ded70b1fa000767e2531db55cce58 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski krzysztof.kozlowski@linaro.org Date: Wed, 14 Aug 2024 21:58:21 +0200 Subject: [PATCH] thermal: of: Fix OF node leak in thermal_of_trips_init() error path

Terminating for_each_child_of_node() loop requires dropping OF node reference, so bailing out after thermal_of_populate_trip() error misses this. Solve the OF node reference leak with scoped for_each_child_of_node_scoped().
