Message-Id: <1218993826-4571-2-git-send-email-petkovbb@gmail.com>
Date: Sun, 17 Aug 2008 19:23:42 +0200
From: Borislav Petkov <petkovbb@...glemail.com>
To: Bartlomiej@...lum.tnic, Zolnierkiewicz@...lum.tnic,
<bzolnier@...il.com>

Subject: [PATCH 1/5] ide: unify conversion macros
Introduce to_ide_dev() and ide_drv_g() macros and replace the respective
definitions of similar ones in each driver.
There should be no functionality change resulting from this patch.
