From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
Since many data objects may be attached to a single namespace node,
acpi_ns_delete_node() should take that into account and delete all
of those objects along with the namespace node itself, calling
deletion handlers for all of them in the process. Make that happen.
