    Revert "power: Guard against dividing by 0 in ABS_TO_PERCENTAGE macro"
    
    This reverts commit fcd4e082cc1528b633b7d07732adb2921d244ab8.
    
    This is the wrong fix, as we have gnome-desktop or the backlight
    helper giving us back garbage. We want to fix that, not work-around
    the problem with sticky tape.
