My rationale was that since DRM_DISPLAY_DP_HELPER is not a user-visible symbol but DRM_DP_{AUX_CHARDEV,CEC} are, the latter should be able to be enabled by the user without relying on other drivers to select the required symbols (I would argue that even should select DP_HELPER but that can't be done or otherwise the helper couldn't be built as module).
In other words, either DRM_DP_{AUX_CHARDEV,CEC} can be user selectable as a standalone symbol or can't and will only be visible if other driver selects their required symbols.
In which case, why not just do this non-user visible and just make the drivers using their helpers to select it directly? That is one of the options I proposed before.
So I believe this is the less intrusive change that will preserve the current behaviour as much as possible.
I don't have a strong opinion though and if you prefer I can change to be a depends instead.
