Then don't blindly cast it backwards! Fix that up, an ib device should have access to the dma structures that the PCI device it depends on has. If not, you need to set that up properly in the IB core, don't mess with the driver core for this at all. Somehow all other subsystems work just fine, don't instantly think that the driver core needs to bend to the will of the IB code, because you are somehow "special".
