Subject: [PATCH 02/14] staging: csr: Fixed exceeding 80 chars per line problems on io.c
Date: Tue, 16 Oct 2012 02:24:21 +0900
Message-Id: <1350321868-2613-2-git-send-email-antiroot@gmail.com>

X-Mailing-List: linux-kernel@vger.kernel.org
Content-Length: 15479
Lines: 400

Originally there were a lot of coding style problems including exceeding
80 lines per line.  So I fixed them, but still there is a 'long string'
printing routines which will be modified on the next patch.
