Ah, yes, I recall we had this discussion around the time the ACPI0012
NFIT driver was developed. IIRC the reason ACPI0012 remaining an
acpi_driver was due to a need to handle ACPI notifications, is that
the deciding factor? ACPI0017 does not have any notifications so it
seems like platform driver is the way to go.
