After rebasing on top of the latest code base (with Hans' patches included) I
checked the users of similar code flow and found that there is no sense to
provide this helper now. It's only one user for this API as is, otherwise it
needs an access to struct acpi_device, which the proposed API doesn't provide.

Hence, self-NAK.
