[PATCH 5.17 0751/1126] remoteproc: qcom: Fix missing of_node_put in adsp_alloc_memory_region

[Greg Kroah-Hartman]

From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit 505b5b1616e200042999de715dbe7c1e2735cd65 ]

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

Fixes: dc160e449122 ("remoteproc: qcom: Introduce Non-PAS ADSP PIL driver")
