Merge tag 'pm-5.12-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates from Rafael Wysocki: "These are fixes and cleanups on top of the power management material for 5.12-rc1 merged previously. Specifics: - Address cpufreq regression introduced in 5.11 that causes CPU frequency reporting to be distorted on systems with CPPC that use acpi-cpufreq as the scaling driver (Rafael Wysocki). - Fix regression introduced during the 5.10 development cycle related to CPU hotplug and policy recreation in the qcom-cpufreq-hw driver (Shawn Guo). - Fix recent regression in the operating performance points (OPP) framework that may cause frequency updates to be skipped by mistake in some cases (Jonathan Marek). - Simplify schedutil governor code and remove a misleading comment from it (Yue Hu). - Fix kerneldoc comment typo in the cpufreq core (Yue Hu)" * tag 'pm-5.12-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: Fix typo in kerneldoc comment cpufreq: schedutil: Remove update_lock comment from struct sugov_policy definition cpufreq: schedutil: Remove needless sg_policy parameter from ignore_dl_rate_limit() cpufreq: ACPI: Set cpuinfo.max_freq directly if max boost is known cpufreq: qcom-hw: drop devm_xxx() calls from init/exit hooks opp: Don't skip freq update for different frequency
