Merge branch 'pm-sleep'

Merge updates related to system suspend and hibernation for
6.20-rc1/7.0-rc1:

 - Stop flagging the PM runtime workqueue as freezable to avoid system
   suspend and resume deadlocks in subsystems that assume asynchronous
   runtime PM to work during system-wide PM transitions (Rafael Wysocki)

 - Drop redundant NULL pointer checks before acomp_request_free() from
   the hibernation code handling image saving (Rafael Wysocki)

 - Update wakeup_sources_walk_start() to handle empty lists of wakeup
   sources as appropriate (Samuel Wu)

 - Make dev_pm_clear_wake_irq() check the power.wakeirq value under
   power.lock to avoid race conditions (Gui-Dong Han)

 - Avoid bit field races related to power.work_in_progress in the core
   device suspend code (Xuewen Yan)

* pm-sleep:
  PM: sleep: core: Avoid bit field races related to work_in_progress
  PM: sleep: wakeirq: harden dev_pm_clear_wake_irq() against races
  PM: wakeup: Handle empty list in wakeup_sources_walk_start()
  PM: hibernate: Drop NULL pointer checks before acomp_request_free()
  PM: sleep: Do not flag runtime PM workqueue as freezable
