Title:
  Brightness control broken on XPS13 with 3.8.0-16 and 3.8.0-22

Status in The Linux Kernel:
  Incomplete
Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Raring:
  Fix Released

Bug description:
  Since 3.8.0-16, the brightness control doesn’t work anymore.
  The popup is displayed, so the shortcut keys do work correctly, but it has no effect on the actual brightness of the screen.

  Switching back to 3.8.0-15 solves the issue.
