Since the pci_dev is no longer held in the provate data, we can
also cleanup the detach a bit. Remove the IS_ENABLED() tests in
the detach. If the pci_dev is non NULL it's a PCI device otherwise
it's an ISA device. Using IS_ENABLED() to omit the code paths
makes the code a bit confusing and doesn't save much.
No, you really need to check thisboard->bustype in the detach() because
hw_dev might be NULL for a PCI board if the attach() failed.
Actually, your patch wouldn't do any harm as dev->iobase would be 0. It
would just go through the "failed ISA device" path instead of the
"failed PCI device" path. It would be more robust to check
