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

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

From: Ilia Mirkin <[email protected]>

commit b25b4427e9dfba073cf9bc86603956ed395eb6e3 upstream.

The intent was to only enable it by default for optimus, e.g. see the
runtime_idle callback. The suspend callback may be called directly, e.g.
as a result of nouveau_crtc_set_config.
