The recent commit [3ea87855: drm/helper: lock all around force mode restore] introduced drm_modeset_lock_all() in drm_helper_resume_force_mode() itself, while exynos driver takes this lock before calling it. Move the function call outside the lock for avoiding a deadlock.

This patch had already been posted but your patch comments what was the problem more exactly than below one. http://www.spinics.net/lists/dri-devel/msg58586.html
So picked it up instead of previous one.
Thanks, Inki Dae
