From 34c7b3ac4ccb6a972f81a4102c8ef216ca1fb155 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 31 Aug 2016 10:05:25 +0200 Subject: 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/) // @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 --- drivers/rtc/rtc-mcp795.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/rtc/rtc-mcp795.c') diff --git a/drivers/rtc/rtc-mcp795.c b/drivers/rtc/rtc-mcp795.c index 025bb33b9cd2..4021fd04cb0a 100644 --- a/drivers/rtc/rtc-mcp795.c +++ b/drivers/rtc/rtc-mcp795.c @@ -151,7 +151,7 @@ static int mcp795_read_time(struct device *dev, struct rtc_time *tim) return rtc_valid_tm(tim); } -static struct rtc_class_ops mcp795_rtc_ops = { +static const struct rtc_class_ops mcp795_rtc_ops = { .read_time = mcp795_read_time, .set_time = mcp795_set_time }; -- cgit v1.2.3
