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. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> --- Changes since v1: - Store msm_dp reference in dpu_encoder_virt instead of carrying a list of them and searching repeatedly drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 23 ++++++++++++--------- 1 file changed, 13 insertions(+), 10 deletions(-)
