I was of two minds before sending this patch with above Fixes lines: 
This change is because of IOVA but at the time IOVA patch was 
introduced, this bus was not part of master. So, ideally, in the 
net-next itself the integration should have been with fixed code - but, 
I ended up verifying base patches without IOVA patches (some earlier 
snapshot of net-next).

Anyways, I will send another patch with IOVA as fix line.
