Assuming this is a shorthand for defining two platform devices for two ASoC cards I'd suggest that you instead move towards registering clocks for the DAIs and probing them as platform devices - take a look at how the PXA AC97 driver now does this for an example. The soc-audio device will hopefully get removed at some point and you can't guarantee that the user won't want to put the two DAIs into a single sound card.
