[PATCH 5.15 388/667] soc: qcom: smp2p: Fix missing of_node_put() in smp2p_parse_ipc

From: Greg Kroah-Hartman
Date: Tue Jun 07 2022 - 15:28:26 EST


From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit 8fd3f18ea31a398ecce4a6d3804433658678b0a3 ]

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