I have updated the patch with the changes in v8, please do review. > > -- > With best wishes > Dmitry Thanks Vinod P.

Update crtc retrieval from dpu_enc to dpu_enc connector state, since new links get set as part of the dpu enc virt mode set. The dpu_enc->crtc cache is no more needed, hence cleaning it as part of this change.
