Hi Takashi,

Today's linux-next build (x86_64 allmodconfig) failed like this:

Caused by commit ff7bf02f630ae93cad4feda0f6a5a19b25a5019a ("ASoC: fix
documentation in CS4270 codec driver") which does somewhat more than fix
documentation.  It clearly wasn't even build tested.

I have dropped the sound tree for today.
