ACPI enumerated PNP devices neither are PNP cards, nor have those magic strings in device names, so this mechamism never actually works for ACPI enumerated PNPCXXX/PNPDXXX devices. Consequently, it is safe to remove those two IDs from the PNP ACPI scan handler's device ID list. Signed-off-by: Zhang Rui [rjw: Subject and changelog] Signed-off-by: Rafael J.
