Hi Alex,

Do we need to apply David's patch [1] to drm-misc-next? If so, I can 
merge it there. Also, I noticed that drm-misc-next changed the dp header 
path; in that way, I had to change the original patch a little bit.

1. https://patchwork.freedesktop.org/patch/480331/?series=102035&rev=1

Best Regards,
Siqueira
