Sure, fine with me.

This is good information, but does it have to come in such a scary message?
It appears that something is wrong with the device, when in fact, it just
doesn't support an optional capability.

Could we demote the message to e.g. ACPI_DB_INFO?

I already moved this one with the big debug to error/warn ... patch.
It should now be ACPI_DB_INFO, but I did not add the device name though...
