Subject: [CI 2/2] drm/i915: Show PCI power state under debugfs/i915_runtime_pm_status
Date: Sun,  3 Apr 2016 14:14:21 +0100	[thread overview]
Message-ID: <1459689261-7920-2-git-send-email-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <1459689261-7920-1-git-send-email-chris@chris-wilson.co.uk>

As the current PCI power state is an essential feature of runtime pm,
include it in the debugfs/i915_runtime_pm_status.

v2: Use pci_power_name()
