If anyone has any objections, please let me know. ------------------ From: Hans de Goede commit bbf038618a24d72e2efc19146ef421bb1e1eda1a upstream. Just like many other Samsung models, the 670Z5E needs to use the acpi-video backlight interface rather then the native one for backlight control to work, add a quirk for this.
