The acpi pnp scan handler id list just copies all the ids from all the struct pnp_device_id instances, but some of them do not comply with the ACPI PNP id rule (3 Alpha Charactors + 4 Hex numbers). For those ids, the coressponding devices will never be enumerated via ACPI, so it is safe to remove those ids from the PNPACPI white list.
