Which nobody should be doing since it's already totally broken for
something to be using this on the DT side except in the one case of the
Rohm device which is listed there.  I don't want to merge anything which
allows the breakage we're seeing with people putting spidev in their DTs
to be propagated into ACPI, at most we should have something that
specifically identifies individual devices only.
