[igt-dev] [PATCH i-g-t] igt/pm_rpm: Show the contents of i915_runtime_pm_status on setup

[Chris Wilson]

To try and help debug situations where the driver has leaked a runtime
reference before executing the pm_rpm tests, show the contents of
i915_runtime_pm_status at startup, which will include all currently held
wakerefs.
