Subject: [PATCH 5/6] drm/i915: Get runtime pm ref on i915_guc_load_status_info
Date: Mon, 14 Dec 2015 19:14:27 +0200	[thread overview]
Message-ID: <1450113268-12183-5-git-send-email-mika.kuoppala@intel.com> (raw)
In-Reply-To: <1450113268-12183-1-git-send-email-mika.kuoppala@intel.com>

Getting guc load status does hardware access so it needs
to have pm ref.
