Thank you!

I can do this, but I avoided it because in most of the uses in the
kernel currently there's no struct acpi_device, they're just passing
ACPI_HANDLE(dev) instead, so I'd need to get the adev with
ACPI_COMPANION() in each place. It didn't seem worth it...but happy to
do it if you'd prefer it that way?
