Commit Message

Philipp Stanner Sept. 2, 2024, 6:23 a.m. UTC 
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()").

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().
