Comment # 33 on bug 1182552 from Takashi Iwai

The fixes have been pushed to SLE15-SP2 branch and will be merged soon later.
Unfortunately, it slipped from the upcoming update kernel, so it'll be merged
likely in the next update in April.  Until then, you can keep my patched kernel
or use the workaround by copying the old kernel module.

I close this bug now.  Thank you for patient testing!
