2017-02-24watchdog: constify watchdog_info structuresBhumika Goyal1-1/+1
Declare watchdog_info structures as const as they are only stored in the info field of watchdog_device structures. This field is of type const struct watchdog_info *, so watchdog_info structures having this property can be declared const too. Done using Coccinelle: @r1 disable optional_qualifier@ identifier i; position p; @@ static struct watchdog_info i@p={...}; @ok@ identifier r1.i; position p; struct watchdog_device obj; @@ obj.info=&i@p; @bad@ position p!={r1.p,ok.p}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct watchdog_info i; Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Acked-by: Florian Fainelli <f.fainelli@gmail.com> Acked-by: Baruch Siach <baruch@tkos.co.il> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Adam Thomson <Adam.Thomson.Opensource@diasemi.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-09-24watchdog: constify watchdog_ops structuresJulia Lawall1-1/+1
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. 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 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> 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>
