Subject: [PATCH] acpi_video: Add enable_native_backlight quirk for
|
|
|
bd2ec3d |
MacbookPro12,1

It seems that the latest generation of MacbookPro needs to use the
|
|
|
bd2ec3d |
native backlight driver, just like most modern laptops do, but it does
|
|
|
bd2ec3d |
not automatically get enabled as the Apple BIOS does not advertise
|
|
|
bd2ec3d |
Windows 8 compatibility. So add a quirk for this.
