Merge branch 'acpi-enumeration'
* acpi-enumeration: ACPI / scan: use platform bus type by default for _HID enumeration ACPI / scan: always register ACPI LPSS scan handler ACPI / scan: always register memory hotplug scan handler ACPI / scan: always register container scan handler ACPI / scan: Change the meaning of missing .attach() in scan handlers ACPI / scan: introduce platform_id device PNP type flag ACPI / scan: drop unsupported serial IDs from PNP ACPI scan handler ID list ACPI / scan: drop IDs that do not comply with the ACPI PNP ID rule ACPI / PNP: use device ID list for PNPACPI device enumeration ACPI / scan: .match() callback for ACPI scan handlers
