Subject: linux-next 20160512 - ACPI issue with screen brightness

next-20160512 sets the screen brightness to about 40%-ish or so, rather
than the 100% intensity I want.

Dell Latitude E6530 laptop.

git bisect tells me:

059500940defe285222d3b189b366dfe7f299cae is the first bad commit

    ACPI/video: export acpi_video_get_levels

    The acpi_video_get_levels is useful for other drivers, i.e. the
    to-be-added int3406 thermal driver, so export it.

but I've stared at the code and don't see what would do this....
