[PATCH 3.16 027/158] sh: fix build error by adding generic ioport_{map/unmap}()

From: Greg Kroah-Hartman
Date: Mon Sep 15 2014 - 17:14:46 EST


3.16-stable review patch. If anyone has any objections, please let me know.

------------------

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.
