• select DRM_DISPLAY_DP_HELPER
• select DRM_DISPLAY_HELPER

Actually, this is wrong since it will prevent DRM_DISPLAY_HELPER to be set as a module (it's tristate while this symbol is bool). I now have a better understanding of the problem and a patch that I believe is the correct one.

I'll post a v2 soon.
