Subject: drm/i915: Add is-wedged flag to intel_engine_dump()
Git-commit: 2d8d1afb4d7d6d88a1ac19010d9a1a9594188ce3
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Comparing the state tested by intel_engine_is_idle() and printed by
intel_engine_dump(), the only bit not shown is whether or not the device
is wedged. Add that little bit of information to the pretty printer so
that if the engine fails to idle we can see why.
