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
