Pull devfreq fixes for 5.19-rc5 from Chanwoo Choi:

"1. Fix devfreq passive governor issue when cpufreq policies are not
    ready during kernel boot because some CPUs turn on after kernel
    booting or others.

    - Re-initialize the vairables of struct devfreq_passive_data when
      PROBE_DEFER happens when cpufreq_get() returns NULL.

    - Use dev_err_probe to mute warning when PROBE_DEFER.

    - Fix cpufreq passive unregister erroring on PROBE_DEFER
      by using the allocated parent_cpu_data list to free resouce
      instead of for_each_possible_cpu().

    - Remove duplicate cpufreq passive unregister and warning when
      PROBE_DEFER.

    - Use HZ_PER_KZH macro in units.h.

    - Fix wrong indentation in SPDX-License line.

 2. Fix reference count leak in exynos-ppmu.c by using of_node_put().

 3. Rework freq_table to be local to devfreq struct

    - struct devfreq_dev_profile includes freq_table array to store
      the supported frequencies. If devfreq driver doesn't initialize
      the freq_table, devfreq core allocates the memory and initializes
      the freq_table.

      On a devfreq PROBE_DEFER, the freq_table in the driver profile
      struct is never reset and may be left in an undefined state. To fix
      this and correctly handle PROBE_DEFER, use a local freq_table and
      max_state in the devfreq struct."
