2016-09-02rtc: constify rtc_class_ops structuresJulia Lawall1-1/+1
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/) // <smpl> @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 = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Baruch Siach <baruch@tkos.co.il> Acked-by: Hans Ulli Kroll <ulli.kroll@googlemail.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
2016-05-20rtc: remove useless DRV_VERSIONAlexandre Belloni1-1/+0
Many drivers are defining a DRV_VERSION. This is often only used for MODULE_VERSION and sometimes to print an info message at probe time. This is kind of pointless as they are all versionned with the kernel anyway. Also the core will print a message when a new rtc is found.

2015-09-05rtc: Drop (un)likely before IS_ERR(_OR_NULL)viresh kumar1-1/+1
IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there is no need to do that again from its callers. Drop it. gemini driver was using likely() for a failure case while the rtc driver is getting registered. That looks wrong and it should really be unlikely. But because we are killing all the unlikely() flags, lets kill that too.

Use resource_size function on resource object instead of explicit computation. No need to set .owner here. The core will do it.
