+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.
