Subject: [PATCH] drm/client: Export drm_client_dev_unregister()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
Export drm_client_dev_unregister() for use by the i915 driver. The
driver does not use drm_dev_unregister(), so it has to clean up the
in-kernel DRM clients by itself.
