Hi,
Could be related (the same?) with [0]. I have a driver (hwrng/exynos-rng) which in probe does: pm_runtime_set_autosuspend_delay(&pdev->dev, EXYNOS_AUTOSUSPEND_DELAY); pm_runtime_use_autosuspend(&pdev->dev); pm_runtime_enable(&pdev->dev); and in remove: pm_runtime_disable(&pdev->dev) Just before unbinding in __device_release_driver() the device is resumed but unfortunately not suspended later. I mean the __device_release_driver()->pm_runtime_put_sync() does not trigger runtime suspend. This leads to leaving the device in active state (e.g. clocks enabled). It does not happen after removal of autosuspend. Also runtime suspend happens after very fast unbind-bind. Best regards, Krzysztof [0] PM regression with commit 5de85b9d57ab PM runtime re-init in v4.5-rc1 http://comments.gmane.org/gmane.linux.power-management.general/70690
