But in a situation where multiple DP instances would exist this means that the caller need to resolve which struct msm_dp relates to the struct drm_encoder at hand. The information for doing this lookup is available inside the DP driver, so update the API to take the struct msm_drm_private and the struct drm_encoder and have the DP code figure out which struct msm_dp the operation relates to.
