mfd: kempld-core: Constify variables that point to const structure
Add const to the declaration of various local variables of type kempld_platform_data for which the referenced value is always only dereferenced or passed to a const parameter, to record the fact that kempld_platform_data_generic is declared as const. The semantic match that finds this issue is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier i,j; @@ const struct i j = { ... }; @ok@ identifier r.i; position p; @@ const struct i@p * @@ identifier r.i; position p != ok.p; @@ * struct i@p * // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Lee Jones <lee.jones@linaro.org>
