Should be fixed with

commit e0f32f78e51b9989ee89f608fd0dd10e9c230652 (tag:
drm-misc-next-fixes-2019-09-18)

    drm/kms: Duct-tape for mode object lifetime checks

which undoes any side-effect of the patch you're pointing at. I am
rather surprised though that this results in a hard-lookup for you,
did you confirm the bisect by reverting that commit on top of latest
upstream?

Cheers, Daniel
