From 34c7b3ac4ccb6a972f81a4102c8ef216ca1fb155 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 31 Aug 2016 10:05:25 +0200 Subject: [PATCH] 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;
