Subject: [PATCH 5.15 616/913] remoteproc: qcom_wcnss: Add missing of_node_put() in wcnss_alloc_memory_region

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

[ Upstream commit 8f90161a66bc3d6b9fe8dde4d9028d20eae1b62a ]

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