-Subject: [PATCH] acpi: video: Allow forcing native backlight on non win8
- machines
-
-The native backlight behavior (so not registering both the acpi-video
-and the vendor backlight driver) can be useful on some non win8 machines
-too, so change the behavior of the video.use_native_backlight=1 or 0
-kernel cmdline option to be: if user has set video.use_native_backlight=1
-or 0, use that no matter if it is a win8 system or not. Also, we will
-put some known systems into the DMI table to make them either use native
-backlight interface or not, and the use_native_backlight_dmi is used to
-reflect that.
