I was a bit surprised to see that these patches missed 4.12, K. Y. ACKed
them:

http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2017-May/105466.html

and no other concerns were expressed.

To my understanding these patches should go through Greg's char-misc
tree. K. Y., Greg, please let me know if I need to rebase/resend.
