I hate having to rain on the parade again ;)
I just developed some doubts, by accident again,
by getting dangerously near sound/isa/als100.c snd_als100_pnpids:
there are many IDs with '@' embedded (at least in this ISA-based PnP code),
thus I guess that code may have had its justification (unless ACPI 5.0
is clearly fully authoritative for this space and thus '@' does not have any
business there any more).
Dito e.g. isa/cmi8330.c.
Hmm, anyone deeply familiar with ISA PnP ID magic? :)
