[PATCH 00/12] ALSA: hda: Reduce CONFIG_PM dependencies

[Takashi Iwai]

The legacy HD-audio drivers contain a fair amount of CONFIG_PM
dependent code.  As nowadays CONFIG_PM is de facto mandatory, this
makes code unnecessarily complex.

This patch series tries to reduce CONFIG_PM dependencies in HD-audio
drivers.

Lightly tested with different config sets.

[PATCH 01/12] ALSA: hda: intel: Reduce CONFIG_PM dependencies

[Takashi Iwai]

snd-hda-intel contains lots of CONFIG_PM dependent code although
CONFIG_PM is almost mandatory nowadays, and it makes the code
unnecessarily complex.

Let's reduce the dependencies of CONFIG_PM in snd-hda-intel driver
code.  I left a few module options to be dependent on CONFIG_PM (which
are visible to users), but other places are either enabled or
optimized by compiler automatically.

__maybe)unused is discouraged nowadays.
We have new PM macros (w/o SET_ prefix) along with pm_ptr() / pm_sleep_ptr()
macros. They are preferred. In complicated cases the PTR_IF() can be used
directly.

Yeah, it was a dilemma there.  There seems no standard macro to use
pm_ptr() for runtime_suspend (there is only RUNTIME_PM_OPS()), so for
avoiding __maybe_unused, I'd have to expand them manually instead.

I'm not sure I got the use case. If we have runtime PM, we use pm_ptr(),
otherwise pm_sleep_ptr().

[PATCH 02/12] ALSA: hda: codec: Reduce CONFIG_PM dependencies

[Takashi Iwai]

CONFIG_PM is almost mandatory nowadays for real systems, but we have
lots of CONFIG_PM dependent code in snd-hda-codec helper code.

Let's reduce the dependencies of CONFIG_PM now.  The only visible
drawback would be a couple of superfluous trace entries for runtime
PM, but we can live with that.
