NAME
       pci_create_legacy_files - create legacy I/O port and memory files

SYNOPSIS
       void pci_create_legacy_files(struct pci_bus * b);

ARGUMENTS
       b
	   bus to create files under

DESCRIPTION
       Some platforms allow access to legacy I/O port and ISA memory space on a per-bus basis. This routine creates the files and ties them into
       their associated read, write and mmap files from pci-sysfs.c

       On error unwind, but don't propogate the error to the caller as it is ok to set up the PCI bus without these files.
