Thanks. The upstream gave yet another try for the approach, and a new kernel is being built again on the same OBS repo, home:tiwai:bsc1190256-2. Also, I'm building one more another test kernel with a different change, just move the input init to a bit later. That's being built in OBS home:tiwai:bsc1190256-3 repo. It'd be appreciated if you can test them later.
