[PATCH] [media] platform: constify vb2_ops structures

Hi,

Thanks for the patch.

Julia Lawall [off-list ref] wrote on Fri [2016-Sep-09 01:59:10 +0200]:

Check for vb2_ops structures that are only stored in the ops field of a
vb2_queue structure.  That field is declared const, so vb2_ops structures
that have this property can be declared as const also.

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 vb2_ops i at p = { ... };

@ok@
identifier r.i;
struct vb2_queue e;
position p;
@@
e.ops = &i at p;

@bad@
position p != {r.p,ok.p};
identifier r.i;
struct vb2_ops e;
@@
e at i@p

@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
 struct vb2_ops i = { ... };
// </smpl>
