Nope, I am aware that the usual pattern here and wait for Lee to show
up.
For this patch there is a bug as I need to update a comment.
I will fix this when I resend after all the patches in flight has
landed. So likely after the next merge window,

Some of the dependent patches in this series are not yet applied.
I have them queued up for processing this weekend, but I missed the -rc6
window for drm-misc so they will likely not hit upstream in the upcoming
merge window.
I can try to expedite it.

But if you have not yet pushed it, please revert this patch.
Then I will resend only when the remaining patches are upstream.
