| Subject: ACPI / video: Add quirk to force acpi-video backlight on Samsung 670Z5E |
| |
| From: Hans de Goede <hdegoede@redhat.com> |
| |
| 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. |
