Linus Torvalds abdf766d14 More power management updates 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)
 
  - Make pm_runtime_put*() family of functions return 1 when the
    given device is already suspended which is consistent with the
    documentation (Brian Norris)
 
  - Add basic kunit tests for runtime PM API contracts and update return
    values in kerneldoc comments for the runtime PM API (Brian Norris,
    Dan Carpenter)
 
  - Add auto-cleanup macros for runtime PM "resume and get" and "get
    without resume" operations, use one of them in the PCI core and
    drop the existing "free" macro introduced for similar purpose, but
    somewhat cumbersome to use (Rafael Wysocki)
 
  - Make the core power management code avoid waiting on device links
    marked as SYNC_STATE_ONLY which is consistent with the handling of
    those device links elsewhere (Pin-yen Lin)

Pull more power management updates from Rafael Wysocki:
 "These are cpufreq fixes and cleanups on top of the material merged
  previously, a power management core code fix and updates of the
  runtime PM framework including unit tests, documentation updates and
  introduction of auto-cleanup macros for runtime PM "resume and get"
  and "get without resuming" operations.

  Specifics:
