In time: those are for the ones that are included, but that
doesn't have all symbols added. I have another one somewhere
that does a more deeply check. I submitted it as a RFC sometime
ago to the docs ML:

	https://git.linuxtv.org/mchehab/experimental.git/tree/scripts/docs_check_exports?h=doc_export_symbol&id=3f7d1e1b0bcdbe1d95eaa4b256259dfaa08faece

Such script checks only exported symbols.

Thanks,
