Subject: [PATCH 5.10 261/452] soc: qcom: smp2p: Fix missing of_node_put() in smp2p_parse_ipc
From: Miaoqian Lin <linmq006@...il.com>
[ 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.
