More and more, after actually seeing and working with ACPI, I suspect that
you both are right. Maybe (hopefully) though, there is some unified way that can
be made to do this, so that individual drivers won't have to directly code for /
be aware of the differences in the firmware languages (at least, that seemed
to be the intent of the fw_node/device api in the first place). Maybe a
`device_get_child_by_name_or_index` (terribly long name) sort of function
might fill in that gap?

Look also at the solution I proposed in response to Benjamin in my previous
email.
