Interesting, I thought we shouldn't touch ACPI OpRegion for
CONFIG_ACPI=n, but seems that this was changed only in

commit 27d50c82714f6477ac690034b37d202f76eb4f70

    ACPI / i915: Fix incorrect <acpi/acpi.h> inclusions via <linux/acpi_io.h>

So this patch here doesn't change the fact, and since there hasn't been
complaints after the above commit, I wouldn't worry too much.

BR,
Jani.
