Subject: [ 62/75] nouveau: initialise has_optimus variable.

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

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

From: Dave Airlie <airlied@...hat.com>

commit addde4ec31456c5f1e9b61aae3edcfeb0f338f87 upstream.

We should initialise this to 0 really to avoid getting false positives.
