From: Clint Taylor <clinton.a.taylor@xxxxxxxxx>
In commit dc911f5bd8aa ("drm/i915/edp: Allow alternate fixed mode for eDP
if available."), the patch was always selecting the alternate refresh rate
even though user space was asking for the higher rate. This patch adds a
check for vrefresh rate as well as the rest of the mode geometry.
V2: use clock instead of vrefresh for compare.
Fixes: dc911f5bd8aac ("Allow alternate fixed mode for eDP if available.")
