  PM / s2idle: Rename ->enter_freeze to ->enter_s2idle
  PM / s2idle: Rename freeze_state enum and related items
  PM / s2idle: Rename PM_SUSPEND_FREEZE to PM_SUSPEND_TO_IDLE
  ACPI / PM: Prefer suspend-to-idle over S3 on some systems
  platform/x86: intel-hid: Wake up Dell Latitude 7275 from suspend-to-idle
  PM / suspend: Define pr_fmt() in suspend.c
  PM / suspend: Use mem_sleep_labels[] strings in messages
  PM / sleep: Put pm_test under CONFIG_PM_SLEEP_DEBUG
  PM / sleep: Check pm_wakeup_pending() in __device_suspend_noirq()
  PM / core: Add error argument to dpm_show_time()
  PM / core: Split dpm_suspend_noirq() and dpm_resume_noirq()
  PM / s2idle: Rearrange the main suspend-to-idle loop
