   8 commit e04aca4a769e16cf4f9b8a4bd3e761711640dc46 upstream.
   9
  10 Fix build error as reported by Geert Uytterhoeven here:
  11
  12   http://kisskb.ellerman.id.au/kisskb/buildresult/11607865/
  13
  14 The error happens when CONFIG_HAS_IOPORT_MAP=n because of which there
  15 are missing definitions of ioport_map/unmap().  Fix this build error by
  16 adding these prototypes.
