Merge branch 'pm-sleep'

Merge updates related to system sleep for 6.17-rc1:

 - Extend the asynchronous suspend and resume of devices to handle
   suppliers like parents and consumers like children (Rafael Wysocki)

 - Make pm_runtime_force_resume() work for drivers that set the
   DPM_FLAG_SMART_SUSPEND flag and allow PCI drivers and drivers that
   collaborate with the general ACPI PM domain to set it (Rafael
   Wysocki)

 - Add kernel parameter to disable asynchronous suspend/resume of
   devices (Tudor Ambarus)

 - Drop redundant might_sleep() calls from some functions in the device
   suspend/resume core code (Zhongqiu Han)

 - Fix the handling of monitors connected right before waking up the
   system from sleep (tuhaowen)

 - Clean up MAINTAINERS entries for suspend and hibernation (Rafael
   Wysocki)

 - Fix error code path in the KEXEC_JUMP flow and drop a redundant
   pm_restore_gfp_mask() call from it (Rafael Wysocki)

 - Rearrange suspend/resume error handling in the core device suspend
   and resume code (Rafael Wysocki)

 - Fix up white space that does not follow coding style in the
   hibernation core code (Darshan Rathod)
