Noted (queued)... fine by me, and makes life easier.

I don't think moving this into the common helper makes any sense, as
it's only ever done for the eisa adapter. Just keep it local there.

+ ha->ccb_phys = pci_map_single(ha->pdev, &ha->cmdext,
+ sizeof(gdth_cmd_str), PCI_DMA_BIDIRECTIONAL);

Same here.

hmmmmm. We'll see how it plays out... on the remove side, the above is exact what happens in gdth_remove_one() without my patch, thus consolidating two cases of the same code into one. There is a less-strong argument for doing the allocation that way, but it may turn out to be useful anyway once the ISA/EISA API conversion is complete.
