Title
remoteproc: qcom_q6v5_mss: Fix some leaks in q6v5_alloc_memory_region
Summary
In the Linux kernel, the following vulnerability has been resolved: remoteproc: qcom_q6v5_mss: Fix some leaks in q6v5_alloc_memory_region The device_node pointer is returned by of_parse_phandle() or of_get_child_by_name() with refcount incremented. We should use of_node_put() on it when done. This function only call of_node_put(node) when of_address_to_resource succeeds, missing error cases.
