Subject: [PATCH 3.16.y-ckt 001/254] samsung-laptop: Add broken-acpi-video quirk for NC210/NC110

3.16.7-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans de Goede <hdegoede@...hat.com>

commit 5a1426c99f9b7aa11d60c4e6b7a3211bb5321696 upstream.

The acpi-video backlight interface on the NC210 does not work, blacklist it
and use the samsung-laptop interface instead.
