[PATCH v2] x86/platform/intel-mid: Replace deprecated PCI functions

From: Philipp Stanner
Date: Mon Nov 11 2024 - 05:37:11 EST


pcim_iomap_table() and pcim_request_regions() have been deprecated in
commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(),
pcim_iomap_regions_request_all()") and commit d140f80f60358 ("PCI:
Deprecate pcim_iomap_regions() in favor of pcim_iomap_region()"),
respectively.

Replace these functions with pcim_iomap_region().

Additionally, pass the actual driver name to pcim_iomap_region()
instead of the previous pci_name(), since the 'name' parameter should
always reflect which driver owns a region.
