    ALSA: hda - Embed bus into controller object · a41d1224

    ... and replace with the existing hda-core helper codes.
    This reduces lots of lines, finally.
    
    Since struct hda_bus is now embedded into struct azx,
    snd_hda_bus_new() is moved and expanded from hda_codec.c to
    hda_controller.c, accordingly.  Also private_free bus ops and
    private_data field are removed because we no longer need to point azx
    object from bus (we can use container_of())
    
    The spin locks are consolidated into the single one, bus->reg_lock.
