Hi

I made some slight mistakes on yesterday's patch, and I also forgot to revert
one commit. Can you please test
http://cgit.freedesktop.org/~pzanoni/linux/?h=edp-reverts ? Please _make sure_
you're on the edp-reverts branch, and also please make sure you're using
i915.edp_delays=4 and drm.debug=0xe as the Kernel command line parameter.

After you boot, please also run dmesg | grep "eDP delays" just to make sure
you're using the right option :)

If this works for you, you can try reverting the top commits until it stops
working.

Thanks,
Paulo
