[PATCH v1 1/4] drm/msm/mdp5: stop overriding drvdata

[Dmitry Baryshkov <dmitry.baryshkov@linaro.org>]

The rest of the code expects that master's device drvdata is the
struct msm_drm_private instance. Do not override the mdp5's drvdata.

Fixes: 6874f48bb8b0 ("drm/msm: make mdp5/dpu devices master components")
