Pull more power management updates from Rafael Wysocki: "These improve hybrid processors support in intel_pstate, fix an issue in the core devices PM code, clean up the handling of dedicated wake IRQs, update the Energy Model documentation and update MAINTAINERS. Specifics: - Make the HWP performance levels calibration on hybrid processors in intel_pstate more straightforward (Rafael Wysocki). - Prevent the PM core from leaving devices in suspend after a failing system-wide suspend transition in some cases when driver PM flags are used (Prasad Sodagudi). - Drop unused function argument from the dedicated wake IRQs handling code (Sergey Shtylyov). - Fix up Energy Model kerneldoc comments and include them in the Energy Model documentation (Lukasz Luba). - Use my kernel.org address in MAINTAINERS insead of the personal one (Rafael Wysocki)" * tag 'pm-5.15-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: MAINTAINERS: Change Rafael's e-mail address PM: sleep: core: Avoid setting power.must_resume to false Documentation: power: include kernel-doc in Energy Model doc PM: EM: fix kernel-doc comments cpufreq: intel_pstate: hybrid: Rework HWP calibration ACPI: CPPC: Introduce cppc_get_nominal_perf() PM: sleep: wakeirq: drop useless parameter from dev_pm_attach_wake_irq()
