Subject: [PATCH 1/1] sh: Fix build error by adding generic ioport_{map/unmap}()
Date: Tue, 05 Aug 2014 19:25:08 +0000 [thread overview]
Message-ID: <1407266709-9296-1-git-send-email-bobby.prani@gmail.com> (raw)
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.
