Just thought it worth mentioning, this new patch that fixes sound
again, seems to have ressurected an old issue with PLL unlock. I'm
seeing journal entries after fresh boot ......

```
picard kernel: max98090 i2c-193C9890:00: PLL unlocked
picard systemd[462]: Started Sound Service.
picard kernel: max98090 i2c-193C9890:00: PLL unlocked
picard kernel: max98090 i2c-193C9890:00: PLL unlocked
picard kernel: max98090 i2c-193C9890:00: PLL unlocked
picard kernel: max98090 i2c-193C9890:00: PLL unlocked
picard kernel: max98090 i2c-193C9890:00: PLL unlocked
picard kernel: max98090 i2c-193C9890:00: PLL unlocked
picard kernel: max98090 i2c-193C9890:00: PLL unlocked
picard kernel: max98090 i2c-193C9890:00: PLL unlocked
picard kernel: max98090_pll_work: 141 callbacks suppressed
picard kernel: max98090 i2c-193C9890:00: PLL unlocked
```

sound is ok, but sometimes plugging in headphones spams journal with
those PLL messages, and sound turns into "daleks", and I have to
remove/insert headphones few times or stop/start audio to fix it.
It's a very old issue, maybe you'd know more about it.

regards
