I thought I had previously mentioned that this last check has the
potential to break DT systems, which may be inadvertently relying on the
probe order.
I agree we must do this check for ACPI, but I think that for DT it needs
to be relaxed.
I'm happy to rework that locally, if you can address my comments on
patch 9.
Thanks,
Mark.
