Subject: [PATCH v3] drm/sun4i: Implement drm_driver lastclose to restore fbdev console
The drm_driver lastclose callback is called when the last userspace
DRM client has closed. Call drm_fbdev_cma_restore_mode to restore
the fbdev console otherwise the fbdev console will stop working.
Fixes: 9026e0d122ac ("drm: Add Allwinner A10 Display Engine support")
