--- Comment #4 from Stefan Brüns
Unfortunately, we cannot change kernel configs of existing products. I'm reversioning it to Factory for consideration for future products.
The change was pushed to opensuse-kernel (Mail from Takashi Iwai): ----
Enable INTEL LPSS (Low Power SubSystem) for LynxPoint chipsets (bnc#849125) and DesignWare (platform) i2c bus driver (bnc#849338). The DesignWare i2c driver depends on the clock subsystem.

Thanks, applied to master branch now. Still a question is whether we should fix this for 13.1. I find it'd be OK, but this is a bit intensive change than just enabling a new module, so any others review would be appreciated. Takashi
