The trouble with the ID field is that it's too short and seems likely to create collisions, for example HDA stuff just seems to default to NVidia for nVidia cards which seems very likely to create collisions if someone has two graphics cards in their system.
The default IDs are always unique - see snd_card_set_id_no_lock() in sound/core/init.c . Basically, the suffix will follow the device probe order in this case.
Sure, but the genesis of this patch is that probe order isn't sufficiently stable and we want to avoid names based on it... using the ID will be more likely to work out stable than just pure probe order but it's still got the same issue.
