On patches 4-14: Acked-by: Daniel Vetter <daniel.vetter@xxxxxxxx>
I'll try to haggle for a few more reviews by maintainers as soon as the
first 3 patches have landed, but I think I'll pull them all in about a
month or so latest. Please remind me in case I forget to do that (which is
likely ...).
Thanks a lot for doing this.
