From a00a3c0334997f7932e42f6f22ae1718c183ab83 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 22 Oct 2014 16:06:37 +0200 Subject: [PATCH] samsung-laptop: Add broken-acpi-video quirk for NC210/NC110 commit 5a1426c99f9b7aa11d60c4e6b7a3211bb5321696 upstream. The acpi-video backlight interface on the NC210 does not work, blacklist it and use the samsung-laptop interface instead.
