This looks like you are trying to reimplement some of the generic support provided by the pinctrl framework - please don't do that. It looks like you should be using the standard idle and default states.
However I'm also questioning why this device is using pinctrl at all. As far as I can see from the code it's a dumb external device with just an enable control and hence no pin control support so it's not a device I'd expect to have any pinmux to control. Why is it doing this? There are also substantial problems throughout the relevant code but probably the best thing is just to remove it all.

pin_states[mi2s->curr_state]);
To repeat my previous review comments: use dev_ prints.

This CODEC driver has no DAPM support. I'm surprised this works at all, it's certainly not OK for upstream - you need to implement at least stub DAPM support.
