OpenBSD/src grfWzaZ — sys/dev/acpi acpithinkpad.c
On newer ThinkPads reporting HKEY version > 1, don't claim wscons backlight controls so that acpivout can. This allows using all of the fine-grained backlight BCL steps defined in ACPI (usually 100) instead of the dozen or so available through acpithinkpad's proprietary ACPI or CMOS interfaces. This is also needed for future amdgpu work.
