[PATCH 5.16 0380/1017] ASoC: SOF: Add missing of_node_put() in imx8m_probe

[Greg Kroah-Hartman]

From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ 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.

Fixes: afb93d716533 ("ASoC: SOF: imx: Add i.MX8M HW support")
