[PATCH] Make struct videobuf_queue_ops constant

[PATCH] Make struct videobuf_queue_ops constant

[Jonathan Corbet]

The videobuf_queue_ops function vector is not declared constant, but
there's no need for the videobuf layer to ever change it.  Make it const so
that videobuf users can make their operations const without warnings.
