powerpc/macintosh: constify wf_sensor_ops structures
The wf_sensor_ops structures are only stored in the ops field of a wf_sensor structure, which is declared as const. Thus the wf_sensor_ops structures themselves can be const. Done with the help of Coccinelle. // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct wf_sensor_ops i@p = { ... }; @ok1@ identifier r.i; struct wf_sensor s; position p; @@ s.ops = &i@p @ok2@ identifier r.i; struct wf_sat_sensor s; position p; @@ s.sens.ops = &i@p @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct wf_sensor_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct wf_sensor_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
