Yeah, the problem (now and future) is, our early hardware often have
broken BIOS that does not get the pin-config right.  However I
understand that it's not sane to continue expanding the quick code.

Doesn't that risk introducing many regressions? What would be the
problem if we switch to the generic HDA driver for *new* boards and
leave the old working quicks/models untouched?

OK. Do you expect me to follow the example given by commit 2996bdbaa
("ALSA: hda - Remove ALC662 eeepc-p701 and ecs models")?

Thanks,
