3.8.13.1 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Paulo Zanoni <[email protected]> commit affa935440733a79c5a9eb0e5357e2564ca4b355 upstream. And use it whenever we call code that uses the DDIs. We already have intel_ddi.c and prefix every function with intel_ddi_something instead of haswell_something, so I think replacing the checks with HAS_DDI makes more sense. Just a cosmetical change, yes I know, but I have this OCD...
