This looks weird with the ternery operator and extreme indentation -
could you please at least split the declaration of ret from the call to
make the line length a bit extreme?
I will fix it up

I'm not seeing any other handling that distinguishes between the I2S and
DSP modes anywhere - I'm guessing this is because the device is really
only implementing the DSP modes but because it's mono this is compatible
with the I2S modes? It'd be worth having a comment saying this since
while that would be OK not distinguishing between modes properly is a
common error in drivers so it'd help avoid cut'n'paste issues if someone
uses this code as a reference.
Ah it does do LEFT J and Right J so I will fix this

+}
This is a bit odd - can we not just inline the component registration
rather than having this function?
I will eliminate this completely and move to i2c_probe
