Nirmoy Das 3e31af7c46 drm/i915: Check before removing mm notifier ... commit 01bb1ae35006e473138c90711bad1a6b614a1823 upstream. Error in mmu_interval_notifier_insert() can leave a NULL notifier.mm pointer. Catch that and return early. Fixes: ed29c26911 ("drm/i915: Fix userptr so we do not have to worry about obj->mm.lock, v7.")
