Subject: [PATCH 125/241] drm/radeon: properly track the crtc not_enabled case evergreen_mc_stop()

3.5.7.2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@....com>

commit 804cc4a0ad3a896ca295f771a28c6eb36ced7903 upstream.

The save struct is not initialized previously so explicitly
mark the crtcs as not used when they are not in use.
