Suitable for both 2.4 and 2.6 version of the driver. Applies to scsi-misc-2.6 git tree.
Prevent driver from loading if another driver (i2o) has already claimed the resources associated with the card. Discussion associated with this bug can be referenced at http://bugzilla.kernel.org/show_bug.cgi?id=4940 where it was agreed to use pci_request_regions in both the dpt_i2o and the i2o driver to prevent both drivers loading on the same adapter(s).
