The HP Pavilion dv6 has a non-working acpi_video0 backlight interface and an intel_backlight interface which works fine. Add a force_native quirk for it so that the non-working acpi_video0 interface does not get registered. Note that there are quite a few HP Pavilion dv6 variants, some woth ATI and some with NVIDIA hybrid gfx, both seem to need this quirk to have working backlight control. There are also some versions with only Intel integrated gfx, these may not need this quirk, but it should not hurt there.
