I'm perfectly fine with that (even if the question was not directly
asked to me :-)), except that in the tree you made, I see one patch [1]
that is directly related to the atmel-hlcdc driver and not a
transversal cleanup patch (though I don't have any problem letting you
take that patch).

Just sent a patch adding my name for the atmel-hlcdc driver.
