Any reason for mentioning _TRIGGER_STOP here?
Looks like copy paste error.. no reason for this to be here!!

Comment for kfree depending on _event_ would be advised.
I could probably move this to hw_free callback.

What's the rest of this function for if switch-case does not match? Without hd2_enable_reg > 0 you might as well return immediately.
we could do that too! I will try to clean this bit up in next version.

'Default' made it here, what was not the case for most of other switch-case. Keep code consistent would be appreciated. Moreover, in the following function "wcd934x_config_compander", you do decide to do all the processing directly within switch-case. I see no reason why you should not do that here too.
Again, once switch-case fails to find match, the rest of function does not do much, really.

Missing newline before return - based on format of your other functions.
I agree with you! I will fix such instances + other following suggestions in all the patches!

In the function above, "wcd934x_codec_set_iir_gain", you decided against declaring local 'val' for storing _read32, though here, only for a single use-case, you made a difference. Let's keep it consistent and run with one or the other.
Also, is there any value for assigning gain_reg outside of switch-case?
