OTOH, longname can be really ugly to read, and it can vary because it often embeds address or irq numbers in the string.
Capturing that variation is one of the goals - it should mostly be stable between runs.
If a general name is the goal, how about using shortname instead?
Or use id field, as Jaroslav suggested, but without the card number suffix; then it's unique among multiple cards.
I prefer this (use only ID field). This string can be also set in the user space using sysfs/udev, so the administrator may change it if the default is not ideal.
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.
