The regression was introduced in 3.6 kernel for cleaning up the mode clock handling code in intel_dp.c by the commit [71244653: drm/i915: adjusted_mode->clock in the dp mode_fix]. In the past, the clock of the reference mode was modified in intel_dp_mode_fixup() in the case of eDP fixed clock, and this clock was used for calculating in intel_dp_set_m_n(). This override was removed, thus the wrong mode clock is used for the calculation, resulting in a psychedelic smoking output in the end. This patch corrects the clock to be used in the place. v1->v2: Use intel_edp_target_clock() for checking eDP fixed clock instead of open code as in ironlake_set_m_n().
