  SVN rev 197648 on 2009-09-30 17:05:26Z by jhb
  
  Split the 'video' ACPI lock up into two locks to resolve a LOR with the
  sysctl lock.  The 'video' lock now protects the 'bus' of video output
  devices attached to a graphics adapter.  It is used when iterating over
  the list of outputs, etc.  The 'video_output' lock is used to lock the
  output-specific data similar to a driver lock for the individual video
  outputs.
