drm: review locking for drm_fb_helper_restore_fbdev_mode
... it's required. Fix up exynos and the cma helper, and add a corresponding WARN_ON to drm_fb_helper_restore_fbdev_mode. Note that tegra calls the fbdev cma helper restore function also from it's driver-load callback. Which is a bit against current practice, since usually the call is only from ->lastclose, and initial setup is done by drm_fb_helper_initial_config. Also add the relevant drm DocBook entry. v2: Add promised WARN to restore_fbdev_mode. Reviewed-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
