Commit Message

Philipp Stanner March 24, 2025, 9:29 a.m. UTC 
The PCI functions
  - pcim_iomap_regions() and
  - pcim_iomap_table()
have been deprecated.

Replace them with their successor function, pcim_iomap_region().

Make variable declaration order at closeby places comply with reverse
christmas tree order.
