Message-Id: <1429896055-31680-5-git-send-email-m.grzeschik@pengutronix.de>
Date: Fri, 24 Apr 2015 19:20:38 +0200
From: Michael Grzeschik <m.grzeschik@...gutronix.de>
To: davem@...emloft.net
Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org,
kernel@...gutronix.de
Subject: [PATCH 04/21] ARCNET: whitespace, tab and codingstyle fixes
This patch removes trailing whitespaces in the whole
the ARCNET layer. It also replaces the use of space
with tabs and changes fixes the codingstyle on those lines.
Signed-off-by: Michael Grzeschik <m.grzeschik@...gutronix.de>
