These videobuf_queue_ops structures are only passed as the second
argument to videobuf_queue_vmalloc_init, which is declared as const.
Thus the videobuf_queue_ops structures themselves can be const.
Done with the help of Coccinelle.
// <smpl>

In the first case, there is a second commented call to
videobuf_queue_sg_init with the structure as the second argument. If that
code will be uncommented, the const will remain correct, because the second
parameter of that function is also const.
