[Intel-gfx] [PATCH 0/8] sanitize RPS interrupt enabling/disabling

[Imre Deak]

While fixing [1] I noticed that we can simplify a couple of things in
the RPS enabling/disabling code. So I did that and also fixed one WARN
that we can hit with some of the pm_rpm subtests. Hopefully these
changes also makes it clearer how we avoid the race during RPS interrupt
disabling and makes it less fragile (see the comment in patch 7/8).
