OK, I retest latest -nightly kernel, this issue is gone. Now I paste our bisect
result and verified here, I will track it on -next-queued and -fixes kernel, if
not fixed on these two branch, I will remind you.

drm/i915: use drm_modeset_lock_all
Two exceptions:
- debugfs files only read information which is not related to crtc, so
can stay on the modeset_config lock.
- Same holds for the edp vdd work in intel_dp.c. Add a corresponding
WARN_ON and a comment next to the intel_dp struct fields for
documentation.
