From 8a81cf96f5510aaf9a65d103f7405079a7b0fcc5 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 7 Sep 2023 11:55:18 +0200 Subject: [PATCH] thermal/of: add missing of_node_put() for_each_child_of_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. This was done using the Coccinelle semantic patch iterators/for_each_child.cocci Signed-off-by: Julia Lawall Signed-off-by: Rafael J.
