Maintain const annotations when putting values into the data field of an of_device_id structure, and afterwards when extracting them from the data field of such a structure. This was done using the following semantic patch: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier i,j; const struct j *m; struct i *y; type T; expression x,e; position p; @@ ( y =@p (T)(of_device_get_match_data(...)); | x = of_match_node(...); ... when != x = e ( m = e; | y =@p (T)(x->data); ) ) @s@ identifier r.i,j; @@ const struct i j = { ... }; @t depends on s disable optional_qualifier@ expression e; identifier r.i,x,j,n; struct j *m; struct i *e1; position any r.p; type T; @@ ( +const struct i *x; <+...
