While working on the DP AUX bus code I found a few small things that
should be fixed. Namely the non-devm version of
of_dp_aux_populate_ep_devices() was missing an export. There was also
an extra blank line in a kerneldoc and a kerneldoc that incorrectly
documented a return value. Fix these.

Fixes: aeb33699fc2c ("drm: Introduce the DP AUX bus")

None of these seem critical, so my plan is to land this in
drm-misc-next and not drm-misc-fixes. This will avoid merge conflicts
with future patches.

Changes in v3:
- Patch ("drm/dp: Export symbol / kerneldoc fixes...") split for v3.

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.

-Doug
