[PATCH 5.4 035/215] thermal/drivers: imx: Fix missing of_node_put() at probe time

[Greg Kroah-Hartman]

From: Anson Huang <Anson.Huang@xxxxxxx>

[ Upstream commit b45fd13be340e4ed0a2a9673ba299eb2a71ba829 ]

After finishing using cpu node got from of_get_cpu_node(), of_node_put()
needs to be called.
