[PATCH 1/2] ACPI: video: Add backlight=native DMI quirk for HP Pavilion g6-1d80nr

[Hans de Goede]

The HP Pavilion g6-1d80nr 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.
