It, thus, prevents getting rid of the problematic iomap table mechanism which was deprecated in commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(), pcim_iomap_regions_request_all()"). Make pcim_iounmap_region() public as the successor of pcim_iounmap_regions(). Mark pcim_iomap_regions() as deprecated.

In mtip32xx, these functions can easily be replaced by their respective successors, pcim_request_region() and pcim_iomap(). Moreover, the driver's calls to pcim_iounmap_regions() in probe()'s error path and in remove() are not necessary. Cleanup can be performed by PCI devres automatically. Replace pcim_iomap_regions() and pcim_iomap_table(). Remove the calls to pcim_iounmap_regions().

Furthermore, the driver contains an unneeded call to pcim_iounmap_regions() in its probe() function's error unwind path. Replace the deprecated PCI functions with pcim_iomap_region(). Remove the unnecessary call to pcim_iounmap_regions().
