we now have multiple reports of devices with a single microphone where 
audio is broken without this patch, e.g. 
https://github.com/thesofproject/linux/issues/2451

This patch should be applied to -stable versions all the way to 5.6. It 
would be desirable for 5.5 and 5.4 as well but it will not apply 
cleanly. It's be trivial to provide a modified patch for these earlier 
kernel versions but I don't know what the process might be here?
