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."
