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 = { ... }; Signed-off-by: Gustavo A.
