[Intel-gfx] [PATCH 00/15] More "unclaimed register" fixes

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

Hi

This series fixes a few more "unclaimed register" problems. Some of them are
only visible if you're only using eDP (i.e., the power well is down) and most of
them are only visible if you get a GPU hang. The good thing is that I only get
GPU hangs when I run ZZ_hangman :)

Now when I boot a machine with only eDP the only "unclaimed register" message I
see is right after the audio driver loads. And then if I run ZZ_hangmen I won't
see "unclaimed register" messages.

Big series but small patches, most of them trivial.

Thanks,
Paulo
