[PATCH 1/2] acpi/video_detect: Add force_native quirk for Dell XPS 17 L702X

[Hans de Goede]

The Dell XPS 17 L702X 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 also is an issue with the brightnesskeys on this laptop,
they do not generate key-press events in anyway. That is not solved by
this patch.

[PATCH 2/2] acpi/video_detect: Add force_native quirk for HP Pavilion dv6

[Hans de Goede]

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.

It's always good to say what the oldest -stable series this applies to is.

Anyway, both [1-2/2] applied.
