[PATCH 1/3] [media] dvb-frontends: constify dvb_tuner_ops structures

From: Julia Lawall
Date: Sun Sep 11 2016 - 11:02:40 EST

These structures are only used to copy into other structures, so declare
them as const.

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 dvb_tuner_ops i@p = { ... };

@ok1@
identifier r.i;
expression e;
position p;
@@
e = i@p

@ok2@
identifier r.i;
expression e1, e2;
position p;
@@
memcpy(e1, &i@p, e2)

@bad@
position p != {r.p,ok1.p,ok2.p};
identifier r.i;
struct dvb_tuner_ops e;
@@
e@i@p

@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
struct dvb_tuner_ops i = { ... };
// </smpl>
