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@xxxxxxxxxx/ 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@xxxxxxxxxx/ 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.
