Obviously we can't, for the same reasons we can't know whether there will ever
be a driver which needs to use custom fb_ops. It works fine as it is now for
three different drivers. And other drivers making use of the cma buffer helpers
are likely to have similar requirements, but if we ever get to a point where a
driver needs custom fb_ops it is fairly easy to change it then.
