Merge branch 'pm-sleep'

Merge updates related to system sleep for 6.15-rc1 including fixes,
cleanups and a rework of the "smart suspend" driver flag handling to
avoid issues that may occur when drivers using it depend on some other
drivers:

 - Rework the handling of the "smart suspend" driver flag in the PM core
   to avoid issues hat may occur when drivers using it depend on some
   other drivers and clean up the related PM core code (Rafael Wysocki,
   Colin Ian King).

 - Fix the handling of devices with the power.direct_complete flag set
   if device_suspend() returns an error for at least one device to avoid
   situations in which some of them may not be resumed (Rafael Wysocki).

 - Use mutex_trylock() in hibernate_compressor_param_set() to avoid a
   possible deadlock that may occur if the "compressor" hibernation
   module parameter is accessed during the registration of a new
   ieee80211 device (Lizhi Xu).

 - Suppress sleeping parent warning in device_pm_add() in the case when
   new children are added under a device with the power.direct_complete
   set after it has been processed by device_resume() (Xu Yang).

 - Remove needless return in three void functions related to system
   wakeup (Zijun Hu).

 - Replace deprecated kmap_atomic() with kmap_local_page() in the
   hibernation core code (David Reaver).

 - Remove unused helper functions related to system sleep (David Alan
   Gilbert).

 - Clean up s2idle_enter() so it does not lock and unlock CPU offline
   in vain and update comments in it (Ulf Hansson).

 - Clean up broken white space in dpm_wait_for_children() (Geert
   Uytterhoeven).
