Subject: [PATCH V2] thermal: imx: Add missing of_node_put()
Date:   Thu, 26 Mar 2020 22:29:05 +0800
Message-Id: <1585232945-23368-1-git-send-email-Anson.Huang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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