rtc: constify rtc_class_ops structures
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>
