  ACPI / video: Disable native backlight on Samsung Series 9 laptops

Thanks Aaron Lu for guiding me through my first kernel patch submission.

So this bug will be fixed in Linux 3.20/4.0 and this report here may be closed.

Still I'd like to know if there are any plans to reenable native backlight, now
that we know (thanks Luca Boccassi) that a newer xserver-xorg-video-intel also
fixes the issues. Aaron?

Thanks again
jre/Jens Reyer
