WM8962 crashing on suspend

I have an imx8m Mini with a wm8962 codec.  If I run a speaker test and
suspend the board while the speaker test is running, I get the
following upon wake:

wm8962 3-001a: ASoC: error at soc_component_read_no_lock on wm8962.3-001a: -16

This message repeats itself over and over again.  If I attempt to use
any audio, it fails until I reboot the board.

If I run the audio test, then exit and suspend, the audio works upon
resume, so it appears to be related to suspending while running.

I am hoping someone might have a suggestion as to what I might be able
to do or try to allow this to successfully suspend and resume if the
device is playing sound.

thank you,

adam
