Subject: ACPI / video: Add disable_native_backlight quirk for Samsung 510R
|
|
Origin: https://git.kernel.org/linus/e77a16355a29230b99bafe55834a8252e55308ec
|
|
|
|
Backlight control through the native intel interface does not work properly
|
|
on the Samsung 510R, where as using the acpi_video interface does work, add
|
|
a quirk for this.
