From 6f904d015262dfa43eb1cecc00b0998b4c3543f2 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Wed, 23 Jul 2008 19:55:57 +0200 Subject: [PATCH] ide: add ide_host_add() helper Add ide_host_add() helper which does ide_host_alloc()+ide_host_register(), then convert ide_setup_pci_device[s](), ide_legacy_device_add() and some host drivers to use it. While at it: * Fix ide_setup_pci_device[s](), ide_arm.c, gayle.c, ide-4drives.c, macide.c, q40ide.c, cmd640.c and cs5520.c to return correct error value. * -ENOENT -> -ENOMEM in rapide.c, ide-h8300.c, ide-generic.c, au1xxx-ide.c and pmac.c * -ENODEV -> -ENOMEM in palm_bk3710.c, ide_platform.c and delkin_cb.c * -1 -> -ENOMEM in ide-pnp.c Signed-off-by: Bartlomiej Zolnierkiewicz --- drivers/ide/arm/ide_arm.c | 7 +------ drivers/ide/arm/palm_bk3710.c | 10 ++++------ drivers/ide/arm/rapide.c | 8 ++------ drivers/ide/h8300/ide-h8300.c | 9 +-------- drivers/ide/ide-generic.c | 11 ++++------- drivers/ide/ide-pnp.c | 16 ++++++++-------- drivers/ide/ide-probe.c | 27 +++++++++++++++++++-------- drivers/ide/legacy/buddha.c | 5 +---- drivers/ide/legacy/gayle.c | 7 +------ drivers/ide/legacy/ide-4drives.c | 7 +------ drivers/ide/legacy/ide-cs.c | 8 +++----- drivers/ide/legacy/ide_platform.c | 8 ++------ drivers/ide/legacy/macide.c | 7 +------ drivers/ide/legacy/q40ide.c | 7 +------ drivers/ide/mips/au1xxx-ide.c | 8 ++------ drivers/ide/mips/swarm.c | 10 ++++------ drivers/ide/pci/cmd640.c | 7 +------ drivers/ide/pci/cs5520.c | 7 +------ drivers/ide/pci/delkin_cb.c | 8 +++----- drivers/ide/pci/scc_pata.c | 10 ++++------ drivers/ide/ppc/pmac.c | 9 ++++----- drivers/ide/setup-pci.c | 10 ++-------- include/linux/ide.h | 2 ++ 23 files changed, 72 insertions(+), 136 deletions(-) diff --git a/drivers/ide/arm/ide_arm.c b/drivers/ide/arm/ide_arm.c index 9efd7a8..176532f 100644 --- a/drivers/ide/arm/ide_arm.c +++ b/drivers/ide/arm/ide_arm.c @@ -28,7 +28,6 @@ static int __init ide_arm_init(void) { - struct ide_host *host;
