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/[e-mail]/

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/[e-mail]/

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

Regards,

Hans
