[Yu Ning]

Review: Disapprove

After some further digs I proposed a patch for unity-control-center, please find the details here:
https://code.launchpad.net/~yuningdodo/unity-control-center/unity-control-center.lp1396464-prevent-update-sink-input-in-parallel/+merge/245927

With that patch we don't need to swap the order in u-s-d, I'll close this proposal now.
