Commit Message

Philipp Stanner Aug. 5, 2024, 8:01 a.m. UTC
pcim_iomap_table() and pcim_iomap_regions_request_all() have been
deprecated by the PCI subsystem in commit e354bb84a4c1 ("PCI: Deprecate
pcim_iomap_table(), pcim_iomap_regions_request_all()").

Replace these functions with their successors, pcim_iomap() and
pcim_request_all_regions()

Missing period at the end.

I haven't looked at the implementation differences of those two, but would it
be really an equivalent change now?

Note, the resource may be requested, OR mapped, OR both. In accordance with the
naming above I assume that this is not equivalent change with potential
breakages.

(Yes, I see this).
