[PATCH] ALSA update [8/12] - 2002/09/06

  - VIA686 and VIA8233 driver merge to VIA82xx
  - ioctl32 fixes
  - fixed OOPS in snd_pcm_sgbuf_delete (not initialized)
  - I2C - call hw_stop() before returning at the error pointer
  - AC'97 codec - added more AC97 IDs by Laszlo Melis
  - CS46xx - mutex initialization fix
  - ENS1371 - added one more card to S/PDIF capabilities
  - intel8x0
    - fixed secondary and third codec indexes
  - PPC Keywest - initialize MCS in loop until it succeeds
  - PPC Tumbler - the initial support for snapper (TAS3004) on some tibook
  - USB Audio - mixer fixes
