Great, so the bug was unconditionally unregistering the platform driver when it would fail to attach if none of the legacy IO ports were detected. I think the driver needs a bit of a tidy up. There's no need at all to use ida_get_simple(): the only reason for a dense array of numbers was for storing the hba private data in the array you got rid of; we can now simply use shost->host_no ... it's more useful anyway because the numbers match those SCSI is using. Also, if you insist on converting the printk's to dev warn, you no longer need to print out the driver name ... dev_printk already prints out the device and driver name as the prefix. The if (error == 0) is usually written as if (!error) but that's minor.
