[PATCH 08/18] drm/i915/gen9+: Remove redundant power well state assert during enabling

[Imre Deak]

We check already for power wells that are unexpectedly on (or forced on)
during power well disabling. Those checks also account for other
power well requesters like KVMR or DEBUG. As such this check is
redundant, let's remove it to simplify things.
