drm/exynos: Fix double locks at PM resume
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. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Inki Dae <inki.dae@samsung.com>
