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().

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().

Resources requested through pcim_* functions don't need to be cleaned up manually in the remove() callback or in the error unwind path of a probe() function. Moreover, there is an unnecessary loop which only requests and ioremaps BAR 0, but iterates over all BARs nevertheless. Furthermore, pcim_iomap_regions() and pcim_iomap_table() have been deprecated by the PCI subsystem in commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(), pcim_iomap_regions_request_all()"). Replace these functions with pcim_iomap_region(). Remove the unnecessary manual pcim_* cleanup calls. Remove the unnecessary loop over all BARs.

The bitmask handling code can entirely be removed by replacing pcim_iomap_regions() and pcim_iomap_table(). Replace pcim_iomap_regions() and pcim_iomap_table() with pcim_iomap_region().
