Subject: [PATCH 3.4 165/214] drm/radeon: fix typo in evergreen_mc_resume()

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

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

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

commit 695ddeb457584a602f2ba117d08ce37cf6ec1589 upstream.

Add missing index that may have led us to enabling
more crtcs than necessary.

May also fix:
