Yes, I know. After 5.10, it is easier to track new stuff, as
Sphinx/kernel-doc warnings were all shut up there.

Yeah, some of those are not trivial to address.

FYI, those are called by default after make allmodconfig/allyesconfig.

Make sense. There are lots of kerneldoc warnings for files that 
aren't currently part of the docs building system. It makes sense to
fix those and add them to the Sphinx build logic.

Here, I have a local script that checks for those:

	for i in $(git grep -h "\.\.\s*kernel-doc::" Documentation/|cut -d':' -f 3|grep -vE "\bsource$"|sort|uniq); do
		./scripts/kernel-doc --none $i
	done

It reports 101 warnings against next-20210114.

Thanks,
Mauro
