I landed this one in drm-misc-next:

39c28cdfb719 drm/dp: Export symbol / kerneldoc fixes for DP AUX bus

I chose "drm-misc-next" instead of a "fixes" branch because:
* It's not super urgent.
* I'm still hoping to get review for the other patches in this series
and it would be nice to avoid the conflicts when landing.
