Note that the modules.dep file only tells modprobe "If you're loading module A,
you need to load B first to get some symbols registered". If B is built-in to
the kernel, its EXPORT_SYMBOLS are already available, so it doesn't need to be
listed in modules.dep.

Also, it doesn't record build-time dependencies - it totally assumes that A and B
were built against the same source tree and that Kbuild took care of making sure
that any source code changes to B that affect A caused a rebuild of A to happen.
