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; <+... ( x =@p - (T)(e) + e | x =@p e ) ...+> | m->@e1 n =@p - (T)(e) + e | m->@e1 n =@p e )
@disable optional_qualifier@ identifier t.j,t.n,r.i; @@
struct j { ... + const struct i *n; ... }
@@ identifier x,s.j; type T; @@
struct of_device_id x[] = { ..., { .data = - (T) &j, }, ...};
// </smpl>
