Thanks Lee! > What Acks are you waiting on? What's the merge strategy? I think everything else has been acked by maintainers, except the power-supply parts. I think those have only been looked at by Andreas and Linus W. Haven't heard anything from Sebastian :( I would love to see the patches 1 - 14 and 17 to be merged (via MFD?). I could then re-spin the 15 and 16 to limited audience as I hope Sebastian had time to take a look at them. However, I don't think any of the other patches in the series depend on the last .
