[PATCH] oss: AC97 quirk facility
Add a quirk facility for AC97 in OSS, and add a quirk list for the
i810_audio driver.
This allows automatically "correct" behaviour for sound hardware w/ known
oddities. For example, many cards have the headphone and line-out outputs
swapped or headphone outputs only.
The code is stolen shamelessly from ALSA, FWIW...
