7.02: lrwxrwxrwx 1 root root 0 29 apr 14.27 intel_backlight ->
../../devices/pci0000:00/0000:00:02.0/drm/card1/card1-eDP-1/intel_backlight/

7.1-rc1: lrwxrwxrwx 1 root root 0 29 apr 14.29 intel_backlight ->
../../devices/pci0000:00/0000:00:02.0/drm/card1/card1-eDP-1/intel_backlight/

so the same, and yeah me and Jonas Åhdahl looked at that yesterday,
but seems to be the same but one is less bright on the same brightness
setting, have only sleeped for 4 hours will try to look more properly
later during the week, or hope some newer rc fixes it
