A review of this series would be appreciated. Sorry, swamped, and I was hoping Ville would chime in. ;) The first two patches are trivial, ack. But I'd really like to know what the GOP is doing, and why we're different. Not sure if that's possible. I'm afraid after much bikeshedding there were some file and function renames, and no matter what this series needs a rebase. See [1]. Sorry about the extra effort this causes; I truly appreciate your efforts with the DSI code, and I regret I haven't given this series the love it needs. BR, Jani.
