Hi All,

Here is a patch-series changing gma500's backlight handling to match
the changes done to the other major x86 GPU drivers in the just landed
backlight detection refactor patch series:
https://lore.kernel.org/dri-devel/261afe3d-7790-e945-adf6-a2c96c9b1eff@redhat.com/

The main goal is here is to only register one backlight class device instead
of registering both "acpi_video0" and "psb-bl" backlight class devices;
in preparation for implementing the new backlight userspace-API from:
https://lore.kernel.org/dri-devel/b61d3eeb-6213-afac-2e70-7b9791c86d2e@redhat.com/

Changes in v2:
- Add "Use backlight_get_brightness() to get the brightness" patch

Changes in v3:
- Fix unused variable warnings when CONFIG_BACKLIGHT is not selected by
  marking the 2 variables as  __maybe_unused.

Regards,

Hans
