It's super-fishy looking but actually I think it's OK, at least as things stand now. As you see later from how it's freed:
> pci_free_consistent(h->pdev, sizeof(CommandList_struct), > c, (dma_addr_t) c->busaddr);
this is the bus address of memory from pci_alloc_consistent(), and since cciss never does pci_set_consistent_dma_mask(), the mask will remain at the default 32 bits. So the driver is actually safe in assuming that cmd_dma_handle fits into 32 bits. assuming that cmd_dma_handle.
