It's still wrong order of the patches. Binding should be complete, so
you miss clock-controller in this patch. If you ordered them hoping
there is no dependency between patches, it will not work. You still have
dependency! Your next patch still depends on this, which should be
clearly expressed either in cover letter or next patch.
