    ACPI: video: Add backlight=native DMI quirk for Acer Aspire 3830TG
    
    [ 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.
