[PATCH 3.4 122/177] samsung-laptop: Add broken-acpi-video quirk for NC210/NC110

[lizf]

From: Hans de Goede <hdegoede@xxxxxxxxxx>

3.4.106-rc1 review patch.  If anyone has any objections, please let me know.

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


commit 5a1426c99f9b7aa11d60c4e6b7a3211bb5321696 upstream.

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