    ALSA: ac97: split out the generic ac97 registers · 8e4f7d9b
    Robert Jarzmik 提交于
    Split out from the ac97_codec.h the ac97 generic registers, which can be
    used by a codec, typically a generic ac97 codec, and by the ac97 bus, to
    scan an ac97 AC-Link.
    
    This split encompasses all the AC97 standard registers, but not the
    codec specific ones.
    
    In order to have a clean split between former ac97 bus implementation
    and the new coming one in sound/ac97, it is safer to not include any
    former ac97 includes, excepting in sound/ac97/compat.c.
    
    Amongst the thing to isolate :
     - don't have the struct snd_ac97 in sound/ac97/* (except compat.c) to not
       be "fooled" by a definition which would come with ac97_codec.h by
       "chance".
     - don't have to have snd_a97_*() functions, as they rely on struct
       snd_ac97.
      - don't want the struct snd_ac97_bus_ops, there is a new one
