From: Philipp Stanner <redacted> 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. Signed-off-by: Philipp Stanner <redacted>
