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.
