[PATCH] thermal: imx_sc_thermal: Fix refcount leak in imx_sc_thermal_probe

From: Miaoqian Lin
Date: Mon May 16 2022 - 03:32:11 EST


of_find_node_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Fixes: e20db70dba1c ("thermal: imx_sc: add i.MX system controller thermal support")
