This seems to break linux-next:

Reverting commit b71a717c955a ("drm/msm/mdp5: Update compatible strings

fyi, I updated msm-next over the weekend, which should fix this (and
an unrelated bisectability issue). I guess it should show up in
linux-next soonish..

[PATCH v2 17/25] drm/msm/mdp5: Update compatible strings for MDSS/MDP5
Introduce new compatible strings for the top level MDSS wrapper device,
and the MDP5 device.
Previously, the "qcom,mdp5" and "qcom,mdss_mdp" compatible strings
were used to match the top level platform_device (which was also tied
to the top level drm_device struct). Now, these strings are used
to match the MDP5 platform device.
Use "qcom,mdss" as the compatible string for top level MDSS device.
This is now used to match the top level platform_device (which is
tied to the drm_device struct).
