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 the function pcim_iomap_region().

Perhaps

	clock->reg_base = pcim_iomap_region(pdev, PCI_PTP_BAR_NO,
pci_name(pdev));
	err = PTR_ERR_OR_ZERO(clock->reg_base);
	if (err)

This will make your patch smaller and neater.

P.S. Do you use --histogram diff algo when preparing patches?

So far not.
Should one do that?
