I tried applying the seamingly ready part of the series (patches 3-12),
but this one fails with too many rejects because of the 3ae133b0192b
("drm/msm/dpu: move CRTC resource assignment to
dpu_encoder_virt_atomic_check"), which we picked through msm-fixes.
Unfortunately I can not pick those without a preliminary rebase and
cross-check of this patch and the next one.
