Merge changes related to system sleep, PM domains changes and power
management documentation changes for 5.18-rc1:

 - Fix load_image_and_restore() error path (Ye Bin).

 - Fix typos in comments in the system wakeup hadling code (Tom Rix).

 - Clean up non-kernel-doc comments in hibernation code (Jiapeng
   Chong).

 - Fix __setup handler error handling in system-wide suspend and
   hibernation core code (Randy Dunlap).

 - Add device name to suspend_report_result() (Youngjin Jang).

 - Make virtual guests honour ACPI S4 hardware signature by
   default (David Woodhouse).

 - Block power off of a parent PM domain unless child is in deepest
   state (Ulf Hansson).

 - Use dev_err_probe() to simplify error handling for generic PM
   domains (Ahmad Fatoum).

 - Fix sleep-in-atomic bug caused by genpd_debug_remove() (Shawn Guo).

 - Document Intel uncore frequency scaling (Srinivas Pandruvada).
