Subject: drm: Constify the pretty-print functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The structures and strings involved with various pretty-print functions
aren't meant to be modified, so make them all const. The exception is
drm_connector_enum_list which does get modified in drm_connector_init().
While at it move the drm_get_connector_status_name() prototype from
drmP.h to drm_crtc.h where it belongs.
