You also need to pull in the kerneldoc into the drm.tmpl DocBook template
to include into the drm docs. You can generate those with

$ make htmldocs -k

-k because right now 802 docs are broken :( Also it'd be awesome if you
could include a short DOC: section to describe the design&goal of
drm_bridge quickly and also include that into the DocBook.

For functions which return something it's good to add a Returns: section
describing the semantics of the return codes. Copypasting something
suitable from other kerneldoc is good for consistency ;-)
