From d39b6cfe664079ca79ae1cfebac4725a877fd61d Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Wed, 22 Mar 2006 00:07:53 -0800 Subject: [PATCH] [PATCH] vr41xx: convert to the new platform device interface The patch does the following for v441xx seris drivers: - stop using platform_device_register_simple() as it is going away - mark ->probe() and ->remove() methods as __devinit and __devexit respectively - initialize "owner" field in driver structure so there is a link from /sys/modules to the driver - mark *_init() and *_exit() functions as __init and __exit Signed-off-by: Dmitry Torokhov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/char/vr41xx_giu.c | 19 +++++++++++++------ drivers/char/vr41xx_rtc.c | 30 ++++++++++++++++++++---------- drivers/serial/vr41xx_siu.c | 24 +++++++++++++++--------- 3 files changed, 48 insertions(+), 25 deletions(-) diff --git a/drivers/char/vr41xx_giu.c b/drivers/char/vr41xx_giu.c index 2267c7b817..05e6e814d8 100644 --- a/drivers/char/vr41xx_giu.c +++ b/drivers/char/vr41xx_giu.c @@ -613,7 +613,7 @@ static struct file_operations gpio_fops = { .release = gpio_release, };
