Hi Joe,

Yes, I will add __printf(3,4).  Thanks for pointing this out.

This interface is limited for ACPI, so it should be declared in a header
file under include/acpi.  Among the files in this directory, acpi_bus.h
seems to be a good fit as it declares the interfaces provided by ACPI
core.

Thanks,
