This breaks arm64 builds, would you mind to drop the offending patch
from your linux-next branch?

In case you haven't got time to check, I think the problem is caused
by CONFIG_ACPI_REDUCED_HARDWARE_ONLY being set for arm64 builds. I can
try to fix the problem, if you are busy and want help with it?

Kind regards
