Merge tag 'pm-5.19-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

Pull power management fixes from Rafael Wysocki:
 "These fix some issues in cpufreq drivers and some issues in devfreq:

   - Fix error code path issues related PROBE_DEFER handling in devfreq
     (Christian Marangi)

   - Revert an editing accident in SPDX-License line in the devfreq
     passive governor (Lukas Bulwahn)

   - Fix refcount leak in of_get_devfreq_events() in the exynos-ppmu
     devfreq driver (Miaoqian Lin)

   - Use HZ_PER_KHZ macro in the passive devfreq governor (Yicong Yang)

   - Fix missing of_node_put for qoriq and pmac32 driver (Liang He)

   - Fix issues around throttle interrupt for qcom driver (Stephen Boyd)

   - Add MT8186 to cpufreq-dt-platdev blocklist (AngeloGioacchino Del
     Regno)

   - Make amd-pstate enable CPPC on resume from S3 (Jinzhou Su)"
