Subject[255/272] drm/i915: check eDP encoder correctly when setting modes
2.6.37-stable review patch.  If anyone has any objections, please let us know.

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

From: Jesse Barnes <jbarnes@virtuousgeek.org>

commit 858bc21f0637c407601a05626854ae58b242f75d upstream.

We were using a stale pointer in the check which caused us to use CPU
attached DP params when we should have been using PCH attached params.
