Message-Id: <1429896055-31680-14-git-send-email-m.grzeschik@pengutronix.de>
Date: Fri, 24 Apr 2015 19:20:47 +0200
From: Michael Grzeschik <m.grzeschik@...gutronix.de>

Subject: [PATCH 13/21] ARCNET: com90xx: fix ioaddr prefixes
This patch removes the use of the variable ioaddr in the macros
and uses it directly in the calling functions. This improves
the readability of the code and changes the macros to be used as
offsets.
