The subject is self-explaining :)
Created attachment 149622 [details, diff] linux-mod.eclass.patch
The bug #190934 could be solved together with this one, so I have added it to the dependency graph :)
I have documented almost all the functions inside the eclass but only the functions used in external ebuilds/eclasses are made "visible" in the man page (I have classified some functions as "internal" removing the @ character from the tags used by the awk script).
That's fantastic, thanks so much for writing this.
