[PATCH AUTOSEL 6.1 19/28] thermal/of: add missing of_node_put()

[Sasha Levin <sashal@kernel.org>]

From: Julia Lawall <Julia.Lawall@inria.fr>

[ Upstream commit 8a81cf96f5510aaf9a65d103f7405079a7b0fcc5 ]

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
