It should be ok if you express it as
config ACPI_REDUCED_HARDWARE_ONLY bool "Hardware-reduced ACPI support only" if EXPERT def_bool n depends on ACPI
ArndI am very puzzled. I went back and re-did my configs from before, tried a few new ones, and tried with both expressions above, but I could not get a Kconfig warning. Do you have an example .config that shows the warning?
I don't have a source tree that allows turning on ACPI on arm64 to easily test this. To clarify: the warning will only happen if you also add this piece to arch/arm64/Kconfig:
select ACPI_REDUCED_HARDWARE_ONLY if ACPI
