Ah yes of course - I see it now... The only erroneous case is a scenario that should be fixed by whomever wants to use that. Where as the rest of the "ep - dev" matches become a master driver which has not converted to endpoint matching, during the phase of which subdevices have. Adding this in for v3, along with the rebase to your acpi-graph-cleaned. > > Anyway, I don't think this situation should be a lasting one, and that > endpoint matching is the way to go. Yes, of course hopefully we'll make a full transition along the way. -- Regards Kieran
