[PATCH] - allow multiple ac97 quirks for one piece of hardware

[Matthew Garrett]

snd_ac97_tune_hardware currently exits after applying a single ac97 
quirk. There are bits of hardware (current HPs, for instance) that 
probably want two - MUTE_LED and HP_ONLY. The following trivial patch 
only exits if a quirk fails to apply. I'll send patches adding the 
quirks when I've made sure they work as expected on these machines.

Thanks, the patch looks OK (and Andrew already took it :)

But how about a bit flag, AC97_TUNE_CONTINUE, to indicate to continue
the quirk-parsing, instead of always continueing?
