They can apply the patch series anyway (at least to the patch they are
interested in).

Have the first add that file, and the second assume it comes later in
the sequence.

The wiki page does not talk about drivers... It's a general rule and
applies to all sorts of code. Only add what is really used (this also
refers, for example, to struct definitions for register blocks etc. -
don't try to provide a complete description of your SoC; add only
stuff that is actually used by the code).
