It seems that not only I have to select ACPI_VIDEO, I also have to select all the dependencies. Is this a Kconfig bug or working as intended? i915 seems to have a workaround, so I copied it from there. Except it's currently missing select THERMAL, so I guess it didn't get updated when that got added. ---->8 Having nouveau builtin would still allow ACPI_VIDEO to be used as external module if some of the deps for acpi_video have not been met, which would result in a linking failure. Solve this by selecting all dependencies as well.
