When we added the support for the AUX channel in commit 13afcdd7277e
("drm/bridge: parade-ps8640: Add support for AUX channel") we forgot
to set "drm_dev" to avoid the warning splat at the beginning of
drm_dp_aux_register(). Since everything was working I guess I never
noticed the splat when testing against mainline. In any case, it's
easy to fix. This is basically just like commit 6cba3fe43341 ("drm/dp:
Add backpointer to drm_device in drm_dp_aux") but just for the
parade-ps8640.

That's probably not quite the right tag. I'm going to assume you meant
Reviewed-by? Usually Signed-off-by is added if you were one of the
authors of the patch or you were a maintainer that "touched" the patch
on its way to landing upstream...

Thanks! Since this is pretty trivial/straightforward, I've pushed it.
I ended up pushing it to drm-misc-next instead of drm-misc-fixes to
avoid a merge conflict and because this doesn't seem urgent enough to
justify having to deal with the merge conflict. Please yell if I
should make a different choice in instances like this in the future.
