ACPI: video: Add backlight=native DMI quirk for Acer Aspire 4810T
The Acer Aspire 4810T predates Windows 8, so it defaults to using acpi_video# for backlight control, but this is non functional on this model. Add a DMI quirk to use the native backlight interface which does work properly. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
