Additional power management updates for 5.5-rc1 - Avoid a race condition in the ACPI EC driver that may cause systems to be unable to leave suspend-to-idle (Rafael Wysocki). - Drop the "disabled" field, which is redundant, from struct cpuidle_state (Rafael Wysocki). - Reintroduce device PM QoS frequency constraints (temporarily introduced and than dropped during the 5.4 cycle) in preparation for adding QoS support to devfreq (Leonard Crestez). - Clean up indentation (in multiple places) and the cpuidle drivers help text in Kconfig (Krzysztof Kozlowski, Randy Dunlap).
