rtc: nuc900: stop validating rtc_time in .read_time

2018-03-02T09:12:17+00:00

The RTC core is always calling rtc_valid_tm after the read_time callback. It is not necessary to call it before returning from the callback. Signed-off-by: Alexandre Belloni

rtc: rtc-nuc900: fix loop timeout test

2017-07-06T20:37:16+00:00

We should change this post-op to a pre-op because we want the loop to exit with "timeout" set to zero. Fixes: 0a89b55364e0 ("nuc900/rtc: change the waiting for device ready implement") Signed-off-by: Dan Carpenter Signed-off-by: Alexandre Belloni

rtc: constify rtc_class_ops structures

2016-09-01T23:24:06+00:00

Check for rtc_class_ops structures that are only passed to devm_rtc_device_register, rtc_device_register, platform_device_register_data, all of which declare the corresponding parameter as const. Declare rtc_class_ops structures that have these properties as const. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @r disable optional_qualifier@ identifier i; position p; @@ static struct rtc_class_ops i@p = { ... }; @ok@ identifier r.i; expression e1,e2,e3,e4; position p; @@ ( devm_rtc_device_register(e1,e2,&i@p,e3) | rtc_device_register(e1,e2,&i@p,e3) | platform_device_register_data(e1,e2,e3,&i@p,e4) ) @bad@ position p != {r.p,ok.p}; identifier r.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct rtc_class_ops i = { ... }; // Signed-off-by: Julia Lawall Acked-by: Baruch Siach Acked-by: Hans Ulli Kroll Acked-by: Linus Walleij Acked-by: Thierry Reding Signed-off-by: Alexandre Belloni

rtc: drop owner assignment from platform_drivers

2014-10-20T14:21:31+00:00

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

rtc: rtc-nuc900: remove unnecessary OOM messages

2014-04-03T23:21:17+00:00

The site-specific OOM messages are unnecessary, because they duplicate the MM subsystem generic OOM message. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-nuc900.c: use NULL instead of 0

2013-09-11T22:58:57+00:00

check_rtc_access_enable() returns pointer, thus NULL should be used instead of 0 in order to fix the following sparse warning: drivers/rtc/rtc-nuc900.c:102:16: warning: Using plain integer as NULL pointer Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-nuc900.c: remove empty function

2013-07-03T23:07:53+00:00

After the switch to devm_ functions and the removal of rtc_device_unregister(), the 'remove' function does not do anything. Delete it. Signed-off-by: Sachin Kamat Cc: Wan ZongShun Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-nuc900: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:51+00:00

The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata = NULL when no driver is bound"). Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han Acked-by: Wan Zongshun Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
