    sys/dev/sound/pci    via8233.c 
  Log:
  Add support for (latest) VIA VT8251 (rev. 0x07) audio controller.
  
  A slight difference of this chip from its previous siblings is that
  it need a gentle "wake up" on every (full) DMA buffer completion to
  avoid stalled interrupt handler.
  
  Thanks to George Hartzell for permission on doing remote debugging.
  
  Prime MFC candidate for 6.1-RELEASE. Please reply to this commit if
  there are any objections  (so I won't bug re@),  since the  changes
  are too small and only specific to VT8251.
