Merge branches 'pm-em' and 'pm-runtime'

Merge Energy Model handling code updates and updates of the runtime PM
core code for 6.15-rc1:

 - Clean up the Energy Model handling code somewhat (Rafael Wysocki).

 - Use kfree_rcu() to simplify the handling of runtime Energy Model
   updates (Li RongQing).

 - Add an entry for the Energy Model framework to MAINTAINERS as
   properly maintained (Lukasz Luba).

 - Address RCU-related sparse warnings in the Energy Model code (Rafael
   Wysocki).

 - Remove ENERGY_MODEL dependency on SMP and allow it to be selected
   when DEVFREQ is set without CPUFREQ so it can be used on a wider
   range of systems (Jeson Gao).

 - Unify error handling during runtime suspend and runtime resume in the
   core to help drivers to implement more consistent runtime PM error
   handling (Rafael Wysocki).

 - Drop a redundant check from pm_runtime_force_resume() and rearrange
   documentation related to __pm_runtime_disable() (Rafael Wysocki).

  MAINTAINERS: Add Energy Model framework as properly maintained
  PM: EM: use kfree_rcu() to simplify the code
  PM: EM: Slightly reduce em_check_capacity_update() overhead
  PM: EM: Drop unused parameter from em_adjust_new_capacity()

* pm-runtime:
  PM: runtime: Unify error handling during suspend and resume
  PM: runtime: Drop status check from pm_runtime_force_resume()
  PM: Rearrange documentation related to __pm_runtime_disable()
