Message-Id: <200802020147.29467.bzolnier@gmail.com>
Date: Sat, 2 Feb 2008 01:47:29 +0100
From: Bartlomiej Zolnierkiewicz <bzolnier@...il.com>
To: linux-ide@...r.kernel.org
Cc: linux-kernel@...r.kernel.org, Mikael Starvik <starvik@...s.com>,
Geert Uytterhoeven <geert@...ux-m68k.org>
Subject: [PATCH 3/5] ide: remove ide_setup_ports()
ide-cris.c:
* Add cris_setup_ports() helper and use it instead of ide_setup_ports()
(fixes random value being set in ->io_ports[IDE_IRQ_OFFSET]).
buddha.c:
* Add buddha_setup_ports() helper and use it instead of ide_setup_ports().
falconide.c:
* Add falconide_setup_ports() helper and use it instead of ide_setup_ports(),
also fix return value of falconide_init() while at it.
gayle.c:
* Add gayle_setup_ports() helper and use it instead of ide_setup_ports().
macide.c:
* Add macide_setup_ports() helper and use it instead of ide_setup_ports()
(fixes incorrect value being set in ->io_ports[IDE_IRQ_OFFSET]).
q40ide.c:
* Fix q40_ide_setup_ports() comments.
ide.c:
* Remove no longer needed ide_setup_ports().
