watchdog: constify watchdog_ops and watchdog_info structures
These watchdog_ops and watchdog_info structures are only stored in the ops and info fields of a watchdog_device structure, respectively, which are const. Thus make the watchdog_ops and watchdog_info structures const as well. Done with the help of Coccinelle. The rules for the watchdog_ops case are as follows: // <smpl> @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 = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Linus Walleij <linus.walleij@linaro.org> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
