Rafael J. Wysocki 8c56b5e2a5 ACPI / scan: Annotate physical_node_lock in acpi_scan_is_offline()
commit 4c533c801d upstream.

acpi_scan_is_offline() may be called under the physical_node_lock
lock of the given device object's parent, so prevent lockdep from
complaining about that by annotating that instance with
SINGLE_DEPTH_NESTING.

Fixes: caa73ea158 (ACPI / hotplug / driver core: Handle containers in a special way)
