Well, that patch doesn't depend /on/ anything, but something in the rest
of the series does depend /on it/. As such, this patch can't be merged
completely independently; it has to either:

a) Go into whatever branch the rest of the series goes into.

b) Go into a topic branch in the DT tree, which is then both merged into
the main/regular DT tree /and/ used as a base for the rest of this series.

Dependencies work two ways!

(That is, unless this 1 patch gets merged into 3.14, and the rest of
series doesn't get merged until 3.15. In that case, we can ignore the
dependencies).
