From: Paulo Zanoni <paulo.r.zan...@intel.com>
When I submitted the first patch adding these force wake functions,
Chris Wilson observed that I was using the wrong functions, so I sent
a second version of the patch to correct this problem. The problem is
that v1 was merged instead of v2.
I was able to notice the problem when running the
debugfs-forcewake-user subtest of pm_pc8 from intel-gpu-tools.
V2: - Rebase on the FORCEWAKE_ALL change.
