It seems like latest HyperV sets _ADR to 0 in the ACPI for the VMBS
that's a hardly a good reason to add this.
To me looks like a pointless addition,
_ADR mostly is used when device resides on a bus with standard ennumeration
algorithm (i.e. PCI, ...).
Value is also wrong for the bus it's placed currently,
and with the next patch it won't make a sense altogether.
Pls, drop this patch unless Windows refuses to work without it.
Windows seems to handle fine without this.
