It does not.

I am not using any git tree(s) for this.  Just patches.

That Makefile is in patch-v5.2-rc7-next-20190704.xz.

I don't know how Andrew generates the linux-next.patch file for mmotm,
but I don't see that Makefile anywhere in mmotm, although the rest of
the i915/oa/ files seems to be there.

Maybe diff skips empty files unless told to save them?
