Subject: [PATCH v2] drm/sun4i: Implement drm_driver lastclose to restore fbdev console
Date: Sun,  9 Jul 2017 17:59:51 +1000	[thread overview]
Message-ID: <20170709075951.16690-1-net147@gmail.com> (raw)

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.
