ASoC: Fixes for v5.19

A collection of fixes for v5.19, quite large but nothing major - a good
chunk of it is more stuff that was identified by mixer-test regarding
event generation.

Merge tag 'pm-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"These add support for 'artificial' Energy Models in which power
numbers for different entities may be in different scales, add support
for some new hardware, fix bugs and clean up code in multiple places.

Specifics:

- Update the Energy Model support code to allow the Energy Model to
be artificial, which means that the power values may not be on a
uniform scale with other devices providing power information, and
update the cpufreq_cooling and devfreq_cooling thermal drivers to
support artificial Energy Models (Lukasz Luba).

- Make DTPM check the Energy Model type (Lukasz Luba).

- Fix policy counter decrementation in cpufreq if Energy Model is in
use (Pierre Gondois).

- Add CPU-based scaling support to passive devfreq governor (Saravana
Kannan, Chanwoo Choi).

- Update the rk3399_dmc devfreq driver (Brian Norris).

- Export dev_pm_ops instead of suspend() and resume() in the IIO
chemical scd30 driver (Jonathan Cameron).

- Add namespace variants of EXPORT[_GPL]_SIMPLE_DEV_PM_OPS and
PM-runtime counterparts (Jonathan Cameron).

- Move symbol exports in the IIO chemical scd30 driver into the
IIO_SCD30 namespace (Jonathan Cameron).

- Avoid device PM-runtime usage count underflows (Rafael Wysocki).

- Allow dynamic debug to control printing of PM messages (David
Cohen).

- Fix some kernel-doc comments in hibernation code (Yang Li, Haowen
Bai).

- Preserve ACPI-table override during hibernation (Amadeusz
Sławiński).

- Improve support for suspend-to-RAM for PSCI OSI mode (Ulf Hansson).

- Make Intel RAPL power capping driver support the RaptorLake and
AlderLake N processors (Zhang Rui, Sumeet Pawnikar).

- Remove redundant store to value after multiply in the RAPL power
capping driver (Colin Ian King).

- Add AlderLake processor support to the intel_idle driver (Zhang
Rui).

- Fix regression leading to no genpd governor in the PSCI cpuidle
driver and fix the riscv-sbi cpuidle driver to allow a genpd
governor to be used (Ulf Hansson).

- Fix cpufreq governor clean up code to avoid using kfree() directly
to free kobject-based items (Kevin Hao).

- Prepare cpufreq for powerpc's asm/prom.h cleanup (Christophe
Leroy).

- Make intel_pstate notify frequency invariance code when no_turbo is
turned on and off (Chen Yu).

- Add Sapphire Rapids OOB mode support to intel_pstate (Srinivas
Pandruvada).

- Make cpufreq avoid unnecessary frequency updates due to mismatch
between hardware and the frequency table (Viresh Kumar).

- Make remove_cpu_dev_symlink() clear the real_cpus mask to simplify
code (Viresh Kumar).

- Rearrange cpufreq_offline() and cpufreq_remove_dev() to make the
calling convention for some driver callbacks consistent (Rafael
Wysocki).

- Avoid accessing half-initialized cpufreq policies from the show()
and store() sysfs functions (Schspa Shi).

- Rearrange cpufreq_offline() to make the calling convention for some
driver callbacks consistent (Schspa Shi).

- Update CPPC handling in cpufreq (Pierre Gondois).

- Extend dev_pm_domain_detach() doc (Krzysztof Kozlowski).

- Move genpd's time-accounting to ktime_get_mono_fast_ns() (Ulf
Hansson).

- Improve the way genpd deals with its governors (Ulf Hansson).

- Update the turbostat utility to version 2022.04.16 (Len Brown, Dan
Merillat, Sumeet Pawnikar, Zephaniah E. Loss-Cutler-Hull, Chen Yu)"

PM: EM: Change the order of arguments in the .active_power() callback

The .active_power() callback passes the device pointer when it's called.
Aligned with a convetion present in other subsystems and pass the 'dev'
as a first argument. It looks more cleaner.

Adjust all affected drivers which implement that API callback.
