Merge branch 'pm-core'
* pm-core: (29 commits) dmaengine: rcar-dmac: Make DMAC reinit during system resume explicit PM / runtime: Allow no callbacks in pm_runtime_force_suspend|resume() PM / runtime: Check ignore_children in pm_runtime_need_not_resume() PM / runtime: Rework pm_runtime_force_suspend/resume() PM / wakeup: Print warn if device gets enabled as wakeup source during sleep PM / core: Propagate wakeup_path status flag in __device_suspend_late() PM / core: Re-structure code for clearing the direct_complete flag PM: i2c-designware-platdrv: Optimize power management PM: i2c-designware-platdrv: Use DPM_FLAG_SMART_PREPARE PM / mfd: intel-lpss: Use DPM_FLAG_SMART_SUSPEND PCI / PM: Use SMART_SUSPEND and LEAVE_SUSPENDED flags for PCIe ports PM / wakeup: Add device_set_wakeup_path() helper to control wakeup path PM / core: Assign the wakeup_path status flag in __device_prepare() PM / wakeup: Do not fail dev_pm_attach_wake_irq() unnecessarily PM / core: Direct DPM_FLAG_LEAVE_SUSPENDED handling PM / core: Direct DPM_FLAG_SMART_SUSPEND optimization PM / core: Add helpers for subsystem callback selection PM / wakeup: Drop redundant check from device_init_wakeup() PM / wakeup: Drop redundant check from device_set_wakeup_enable() PM / wakeup: only recommend "call"ing device_init_wakeup() once ...
