Hi, this is a patch series to fix the breakages of eDP output on HP Z1 desktop machine with IvyBridge since 3.6 kernel. The first patch is identical as what I already sent yesterday, reverting a bogus check in the dp train loop. The second one is the patch I cooked today, for using the correct pixel clock for the fixed eDP panel. I guess the second patch won't be applied cleanly to the old kernels, so it'd need to be sent individually to stable kernel if needed. thanks, Takashi
