From 1e815db647ada5f169dc0201b96530e30640d6df Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 21 May 2014 15:39:56 +0200 Subject: [PATCH] ACPI / video: Add use native backlight quirk for the ThinkPad W530 Like all of the other *30 ThinkPad models, the W530 has a broken acpi-video backlight control. Note in order for this to actually fix things on the ThinkPad W530 the commit titled: "nouveau: Don't check acpi_video_backlight_support() before registering backlight" is also needed.
