+Subject: thermal: of: fix OF node leak in of_thermal_zone_find()
+
+From: Joe Hattori <joe@pf.is.s.u-tokyo.ac.jp>
+
+[ Upstream commit 9164e0912af206a72ddac4915f7784e470a04ace ]
+
+of_thermal_zone_find() calls of_parse_phandle_with_args(), but does not
+release the OF node reference obtained by it.
+
+Add a of_node_put() call when the call is successful.
+
+Fixes: 3fd6d6e2b4e8 ("thermal/of: Rework the thermal device tree initialization")
