Yes that is true. Something like this would work?

graph_probe(...)
{
     ...

     if (of_device_get_match_data(dev))
         priv->dpcm_selectable = 1;

     ...
}

Tegra audio graph driver does not require this because already it is 
populating 'force_dpcm' flag and having 'selectable' does not make much 
sense for it.

Right now I am just keeping it to allow current code work. Later you can 
remove this during graph2.

This seems like a better plan, will do this.
