Pushed to drm-misc-fixes, thanks a lot everyone for the acks,
reviews, testing and comments.

drm-misc maintainers, heads-up:

drm-misc-fixes is still based on 4.15-rc8.  The present series
applies cleanly to both 4.15 and 4.16, so I had no need to have
4.16-rc1 backmerged, but that may be necessary sooner or later.
I did a local test pull into drm-fixes, the shortlog looked sane
and it merged and compiled cleanly.

Please note two other commits are still pending in drm-misc-fixes:

    commit 745fd50f3b044db6a3922e1718306555613164b0
    Author: Daniel Vetter <daniel.vetter@ffwll.ch>
    Date:   Wed Jan 31 12:04:50 2018 +0100

    drm/cirrus: Load lut in crtc_commit

Gustavo sent a pull request for this one on Jan 31 but erroneously
based it on the wrong commit and it ended up not being pulled by Dave.

    commit 54f809cfbd6b4a43959039f5d33596ed3297ce16
    Author: Leo (Sunpeng) Li <sunpeng.li@amd.com>
    Date:   Wed Jan 17 12:51:08 2018 +0100

    drm/atomic: Fix memleak on ERESTARTSYS during non-blocking commits

This one has already been pulled by Dave into drm-next for 4.17
as commit 1c6ceeee6ebb but Maarten subsequently cherry-picked
it onto drm-misc-fixes.

Let me know if I've made any mistakes.

Thanks,

Lukas
