SVN rev 198601 on 2009-10-29 15:25:22Z by jhb
MFC 197648:
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.
