From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 5e7a3bf65db57461d0f47955248fcadf37321a74 ]
The Acer Aspire 3830TG 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.
