Is this really necessary? Do we need this with Tegra? Can't we simply assume that there's always only one codec? Or always use a probe_mask of -1? Alternatively, wouldn't this be better off in DT?
This is an option rather for debugging. Usually the codec is recognized automatically in the case of HD-audio.
But, another point is, suppose this is really specific to Tegra and nothing else, whether we need multiple instances. If there is only a single controller, we can omit the arrays.
