What you're saying here is incorrect, as previously discussed at length in this thread:


The two drivers did work together fine until someone in 3.12 changed the PMIC I2C Id
back to just 'da9055' and broke it again. Also, I wanted to add a simple patch to tidy up
the I2C Id names and avoid this but you would not agree. The codec part can be
standalone and by doing what you've done here means that customers would need to
now add additional, unnecessary code to be able to use just the codec driver.
This is not right to me.
