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

As I commented, this might be applicable to 13.1 kernel, though, but I'm also not much convinced by that, hence I didn't apply it to 13.1 branch but only to master branch. That being said, the problem is fixed for FACTORY now, at least, so we may close this as FIXED. If this must be fixed for 13.1 kernel, please discuss with others. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As we don't generally change configs for released kernels, I think we should close as fixed upstream. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
