> changed on GetBrightness
>
>Since commit 793642bfb7("pKbdBacklight: don't cache the brightness level,
>always read it from sysfs attrib"), upower re-gets the actual brigthness
>from sysfs, to deal with hardware with "hardwired" keyboard brightness
>hotkeys.
>
>This commit makes upower also signal (other) users that the brightness has
>changed when the brightness has indeed changed underneath upower.
