Subject: [ 113/173] drm/radeon: fix eDP clk and lane setup for scaled modes

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

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

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

commit 93927f9c1db5f55085457e820f0631064c7bfa34 upstream.

Need to use the adjusted mode since we are sending native
timing and using the scaler for non-native modes.
