From 508db592e2f54d731bf2f5eabd9642a1a566f276 Mon Sep 17 00:00:00 2001 From: Vaishali Thakkar Date: Tue, 7 Jul 2015 11:16:14 +0530 Subject: [PATCH] rtc: ds1685: Use module_platform_driver Use module_platform_driver for drivers whose init and exit functions only register and unregister, respectively. A simplified version of the Coccinelle semantic patch that performs this transformation is as follows: @a@ identifier f, x; @@ -static f(...) { return platform_driver_register(&x); } @b depends on a@ identifier e, a.x; @@ -static e(...) { platform_driver_unregister(&x); } @c depends on a && b@ identifier a.f; declarer name module_init; @@ -module_init(f); @d depends on a && b && c@ identifier b.e, a.x; declarer name module_exit; declarer name module_platform_driver; @@ -module_exit(e); +module_platform_driver(x); Signed-off-by: Vaishali Thakkar Signed-off-by: Alexandre Belloni --- drivers/rtc/rtc-ds1685.c | 22 +--------------------- 1 file changed, 1 insertion(+), 21 deletions(-) diff --git a/drivers/rtc/rtc-ds1685.c b/drivers/rtc/rtc-ds1685.c index 818a3635a8c8..05a51ef52703 100644 --- a/drivers/rtc/rtc-ds1685.c +++ b/drivers/rtc/rtc-ds1685.c @@ -2145,27 +2145,7 @@ static struct platform_driver ds1685_rtc_driver = { .probe = ds1685_rtc_probe, .remove = ds1685_rtc_remove, }; - -/** - * ds1685_rtc_init - rtc module init. - */ -static int __init -ds1685_rtc_init(void) -{ - return platform_driver_register(&ds1685_rtc_driver); -} - -/** - * ds1685_rtc_exit - rtc module exit. - */ -static void __exit -ds1685_rtc_exit(void) -{ - platform_driver_unregister(&ds1685_rtc_driver); -} - -module_init(ds1685_rtc_init); -module_exit(ds1685_rtc_exit); +module_platform_driver(ds1685_rtc_driver); /* ----------------------------------------------------------------------- */ -- 2.20.1
