I didn't do any sort of review of this patch, but I can say that
without it the screen on my sc7180-based device is super glitchy and
when I add this patch in the glitchies are gone.  Thus:

Tested-by: Douglas Anderson <dianders@...omium.org>

...one note is that the subject of this patch seems a bit
non-standard.  I would have expected a tag more like "drm/msm/dpu:"
instead of "msm:disp:dpu1:".  Presumably if the maintainer cares when
landing he/she could fix that up, but something to think about for
future patches.
