True, but if the I2C probe fails, then I would think that the whole system is shot, so this sounds like a very unlikely situation. If you changed the code to clean up after an I2C failure, you could make the whole thing more modular, including eliminating the call to snd_soc_new() in the codec driver.
Since ASoC divides everything into four more-or-less independent drivers, it makes sense that it should be able to handle a situation where one of those drivers just fails to load.
