From: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx> [ Upstream commit 167dac97eb46c7b8a15b2195080e191bb0c9ce35 ] Functions in the DisplayPort code that relates to individual instances (encoders) are passed both the struct msm_dp and the struct drm_encoder. 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. Store a reference to the struct msm_dp associated with each dpu_encoder_virt to allow the particular instance to be associate with the encoder in the following patch.
