Message-Id: <1199366409-26016-3-git-send-email-bbpetkov@yahoo.de>
Date: Thu, 3 Jan 2008 14:20:01 +0100
From: Borislav Petkov <bbpetkov@...oo.de>
To: linux-ide@...r.kernel.org, linux-kernel@...r.kernel.org
Cc: bzolnier@...il.com, Borislav Petkov <bbpetkov@...oo.de>
Subject: [RESEND PATCH 02/10] ide-floppy: move ide-floppy struct and macro defs into its own header. While at it
- do a white-space cleanup
- remove old crufty code untouched since at least 2005
- shorten lines longer than 80ish columns
- shorten some LAAARGE typenames.
There should be no functional changes resulting from this patch.
Signed-off-by: Borislav Petkov <bbpetkov@...oo.de>
