cs42l42_pcm_hw_params() must only configure the PLL if this is the first stream to become active, otherwise it will be overwriting the registers while the PLL is running.

Shouldn't the PLL code be noticing problematic attempts to reconfigure the PLL while it's active rather than the individual callers?
