ACPI: video: Loosen strictness of video bus detection code
BugLink: http://bugs.launchpad.net/bugs/333386
Currently a video bus device must (beside other criteria) define _DOD and
_DOS methods to be considered a video device.
Some broken BIOSes prevented working backlight control by only defining both
for one (non-existing bus) and only _DOD for the rest. With this patch in
place the other bus definitions were considered too and backlight control
started to work again.
