Comment 45 for bug 76881

Thanks. Now I modified the DMI quirk table to adapt more ZenBook models.

A test TW kernel is being built in OBS home:tiwai:bsc1190256-3 repo. It'll be available later at
  http://download.opensuse.org/repositories/home:/tiwai:/bsc1190256-3/standard/

Please give it a try (without probe_defer option). If it's confirmed to work, I'll submit to the upstream and merge to TW and SLE15-SP4 kernels.
