Merge branch 'pm-cpufreq'
Merge cpufreq fixes and cleanups, mostly on top of those fixes, for
6.18-rc1:
- Make cpufreq drivers setting the default CPU transition latency to
CPUFREQ_ETERNAL specify a proper default transition latency value
instead which addresses a regression introduced during the 6.6 cycle
that broke CPUFREQ_ETERNAL handling (Rafael Wysocki)
- Make the cpufreq CPPC driver use a proper transition delay value
when CPUFREQ_ETERNAL is returned by cppc_get_transition_latency() to
indicate an error condition (Rafael Wysocki)
- Make cppc_get_transition_latency() return a negative error code to
indicate error conditions instead of using CPUFREQ_ETERNAL for this
purpose and drop CPUFREQ_ETERNAL that has no other users (Rafael
Wysocki, Gopi Krishna Menon)
- Fix device leak in the mediatek cpufreq driver (Johan Hovold)
- Set target frequency on all CPUs sharing a policy during frequency
updates in the tegra186 cpufreq driver and make it initialize all
cores to max frequencies (Aaron Kling)
- Rust cpufreq helper cleanup (Thorsten Blum)
