watchdog: coh901327_wdt: constify watchdog_ops structure
Check for watchdog_ops structures that are only stored in the ops field of
a watchdog_device structure. This field is declared const, so watchdog_ops
structures that have this property can be declared as const also.
This issue was detected using Coccinelle and the following semantic patch:
@r
disable optional_qualifier@
identifier i;
position p;
@@
static struct watchdog_ops i@p = { ... };
@ok@
identifier r.i;
struct watchdog_device e;
position p;
@@
e.ops = &i@p;
@bad@
position p != {r.p,ok.p};
identifier r.i;
struct watchdog_ops e;
@@
e@i@p
@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
struct watchdog_ops i = { ... };
