[PATCH 5.15 389/667] soc: qcom: smsm: Fix missing of_node_put() in smsm_parse_ipc

From: Greg Kroah-Hartman
Date: Tue Jun 07 2022 - 15:28:28 EST


From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit aad66a3c78da668f4506356c2fdb70b7a19ecc76 ]

The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
