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()
