The patch looks totally bogus to me. It's passing a random struct device from the hbsp host data structure to the dma_map_* routines. which they can't do anything about. The dma_map_* routines only know about some bus types. That's always been the case (that's why you also can't pass a usb device's struct device to them for example). Mostly, PCI, possibly others depending on the platform. So if you are to pass a struct device pointer to dma_map_*, use the one inside the pci_dev of the host. Or have the host driver provide you with the struct device pointer (which is the one from the pci_dev * for PCI implementations, and others give you what they are on, assuming the platform can do dma-* on that device).
