[PATCH] rtc: constify rtc_class_ops structures

On 31/08/2016 at 10:05:25 +0200, Julia Lawall wrote :

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 at p = { ... };

@ok@
identifier r.i;
expression e1,e2,e3,e4;
position p;
@@
(
devm_rtc_device_register(e1,e2,&i at p,e3)
|
rtc_device_register(e1,e2,&i at p,e3)
|
platform_device_register_data(e1,e2,e3,&i at p,e4)
)

@bad@
position p != {r.p,ok.p};
identifier r.i;

@depends on !bad disable optional_qualifier@

@@
static
+const
 struct rtc_class_ops i = { ... };
// </smpl>
