[PATCH 5/6] drm/xen: Use drm_dev_unregister()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



drm_dev_unplug() has been stripped down and is going away. Open code its
2 remaining function calls.

Also remove the drm_dev_is_unplugged() check since this can't be true
before drm_dev_unregister() is called which happens after the check.
