rtc: coh901331: fix a missing check of clk_prepare

2019-01-22T18:01:19Z

clk_prepare() could fail, so let's check its status and if it fails return its error code upstream. Signed-off-by: Kangjie Lu Acked-by: Linus Walleij Signed-off-by: Alexandre Belloni

headers: separate linux/mod_devicetable.h from linux/platform_device.h

2018-07-07T15:52:26Z

At over 4000 #includes, is the 9th most #included header file in the Linux kernel. It does not need , so drop that header and explicitly add to source files that need it. 4146 #include After this patch, there are 225 files that use , for a reduction of around 3900 times that does not have to be read & parsed. 225 #include This patch was build-tested on 20 different arch-es. It also makes these drivers SubmitChecklist#1 compliant.

rtc: stop validating rtc_time after rtc_time_to_tm

2018-03-01T09:49:41Z

rtc_time_to_tm never generates an invalid tm. It is not necessary to validate it. Signed-off-by: Alexandre Belloni

rtc: constify rtc_class_ops structures

2016-09-01T23:24:06Z

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: Fix module autoload for OF platform drivers

2015-09-05T17:37:22Z

These platform drivers have a OF device ID table but the OF module alias information is not created so module autoloading won't work. Signed-off-by: Javier Martinez Canillas Acked-by: Andrew Lunn Signed-off-by: Alexandre Belloni

rtc: drop owner assignment from platform_drivers

2014-10-20T14:21:31Z

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-coh901331: use devm_ioremap_resource()

2014-04-03T23:21:18Z

Use devm_ioremap_resource() in order to make the code simpler, and remove redundant return value check of platform_get_resource() because the value is checked by devm_ioremap_resource(). Signed-off-by: Jingoo Han Acked-by: Linus Walleij Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-coh901331: use platform_{get,set}_drvdata()

2013-07-03T23:07:55Z

Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: rtc-coh901331: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:49Z

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: Linus Walleij Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
