Looking over this a bit, I realise that Broxton suffers from the same
problem, *but* uses a different struct.  I think it'd be best to leave
things the way they are for the time being and try to come up with a
good solution that would work for both platforms without introducing
separate struct pointers to dev_priv (intel_dp while logically the
better option, is trickier to use from intel_ddi, since the function
that would set this up doesn't use intel_dp currently).

Opinions?


Kind regards, David
