Hi all,
After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit
b962a12050a3 ("drm/atomic: integrate modeset lock with private objects")
interacting with commit
eb3dc8978596 ("drm/amd/display: Use private obj helpers for dm_atomic_state")
from Linus' tree (merged during the merge window).
Its not obvious how to fix this up, so I have used the drm-misc tree
from next-20190107 for today.
