Merge branch 'pm-sleep'
* pm-sleep: PM: sleep: Drop dev_pm_skip_next_resume_phases() ACPI: PM: Drop unused function and function header ACPI: PM: Introduce "poweroff" callbacks for ACPI PM domain and LPSS ACPI: PM: Simplify and fix PM domain hibernation callbacks PCI: PM: Simplify bus-level hibernation callbacks PM: ACPI/PCI: Resume all devices during hibernation kernel: power: swap: use kzalloc() instead of kmalloc() followed by memset() PM: sleep: Update struct wakeup_source documentation drivers: base: power: remove wakeup_sources_stats_dentry variable PM: suspend: Rename pm_suspend_via_s2idle() PM: sleep: Show how long dpm_suspend_start() and dpm_suspend_end() take PM: hibernate: powerpc: Expose pfn_is_nosave() prototype
