From: Hans de Goede Date: Thu, 28 May 2015 18:25:46 +0200 Subject: [PATCH] acpi_video: Add enable_native_backlight quirk for MacbookPro12,1 It seems that the latest generation of MacbookPro needs to use the native backlight driver, just like most modern laptops do, but it does not automatically get enabled as the Apple BIOS does not advertise Windows 8 compatibility. So add a quirk for this.
