Hi

This is a resend of the patches I have that fix the runtime PM WARNs we get
while running IGT's pm_pc8 test on Haswell.

Right now, runtime PM is completely broken and these patches should put it back
to the state where it was before. The issue fixed by the first patch completely
breaks runtime PM, so we don't have Bugzilla tags for the other issues because
our QA couldn't even discover them due to the lack of the first patch on our
trees. I have tested this series locally on my Haswell machine and it works.

Thanks,
Paulo
