Ah yes, but longname is still too ugly as an identifier, IMHO.
That's why I'm asking again.

At each time it's shown in kernel messages, I wonder what is that at
all.  It's hard to decode as "Jack..." string appears at the very last
of the name.

Yeah, card->id is no good form.  card->shortname usually contains
the basic vendor and product names but without irq, i/o port or such
information as in longname.
