Hi Mark,
I saw you merged the [PATCH 1/2], the [PATCH 2/2] is also needed. Please take a look.
Thanks,
Hui.

After finishing the playback or recording, the machine driver might call snd_soc_dai_set_pll(codec, pll_id, 0, 0, 0) to stop the internal PLL, but with the codec driver nau8822, it will print error as below: nau8822 0-001a: Unsupported input clock 0 fsl-asoc-card sound-nau8822: failed to stop FLL: -22
Refer to the function wm8962_set_fll() in the codec driver wm8962, if the freq_out is zero, turn off the internal PLL and return 0.
