Date: Fri, 9 May 2014 08:14:15 +0200 From: Takashi Iwai <tiwai@...e.de> To: David Airlie <airlied@...ux.ie> Cc: Daniel Vetter <daniel.vetter@...ll.ch>, dri-devel@...ts.freedesktop.org, linux-kernel@...r.kernel.org Subject: [PATCH 2/2] 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.
