Subject: sh: fix build error by adding generic ioport_{map/unmap}()
From: Pranith Kumar <bobby.prani@xxxxxxxxx>
commit e04aca4a769e16cf4f9b8a4bd3e761711640dc46 upstream.
Fix build error as reported by Geert Uytterhoeven here:
http://kisskb.ellerman.id.au/kisskb/buildresult/11607865/
The error happens when CONFIG_HAS_IOPORT_MAP=n because of which there
are missing definitions of ioport_map/unmap(). Fix this build error by
adding these prototypes.
