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.
