Subject: [PATCH v4 2/3] drm/i915: Move on the new pm runtime interface
Date: Thu, 20 Dec 2018 15:16:57 +0100	[thread overview]
Message-ID: <1545315417-14483-1-git-send-email-vincent.guittot@linaro.org> (raw)

Use the new pm runtime interface to get the accounted suspended time:
pm_runtime_accounted_time_get()
