Subject: [PATCH 5.17 0403/1126] ASoC: SOF: Add missing of_node_put() in imx8m_probe

From: Miaoqian Lin <linmq006@...il.com>

[ Upstream commit 5575f7f49134c7386a684335c9007737c606d3b5 ]

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