Because some endpoint controllers have requirements on the alignment of the controller physical memory address that must be used to map a RC PCI address region, the map PCI start address is not necessarily the desired PCI base address to be mapped. This can result in map_pci_addr being lower than pci_addr as documented. This results in map_size covering the range map_pci_addr..pci_addr+pci_size. The old text had the pci_addr twice instead of map_pci_addr..pci_addr, so replace the erroneous kerneldoc string to reflect the actual range.
