Comment # 21 on bug 1206703 from Takashi Iwai

OK, thanks for confirmation.  It means that the backport of the commit
39bd801d6908900e9ab0cdc2655150f95ddd4f1a
 ASoC: soc-pcm: Don't zero TDM masks in __soc_pcm_open()
is the culprit.

I already pushed the revert to SLE15-SP4 git branch, so that the fix will be
included in the next update kernel.

You can keep my test kernel or use the workaround (copy the module file) until
the next update.
