Patches dropped on the way to 3.11-rc2

[Tim Gardner]

UBUNTU: SAUCE: (no-up) set /proc/acpi/video/*/DOS to 4 by default
UBUNTU: SAUCE: (no-up) Provide a param for allowing the BIOS to handle
changing the brightness on AC/battery status changes.
UBUNTU: SAUCE: (no-up) acpi/video.c: Fix compile warnings

I dropped these patches during the rebase to 3.11-rc2 because of
conflicts, plus the upstream implementation using
acpi_video_backlight_quirks() appears to be superior. As you are among
the signatories, please review for correctness.
