[PATCH 00/11] ASoC: use pm_runtime_resume_and_get() when possible

[PATCH 00/11] ASoC: use pm_runtime_resume_and_get() when possible

[Pierre-Louis Bossart]

After a set of SOF-specific changes, this patchset correct problematic
uses of pm_runtime_get_sync() in ASoC, or simplifies the flow with no
functional changes. Two patches for Intel platforms also add a test on
resume success.

Additional changes were initially suggested to completely remove the
use of pm_runtime_get_sync(). These changes were dropped since they
are way too invasive, specifically in cases where the return values
were not tested, which would lead to duplicate pm_runtime_put(). The
remaining uses of pm_runtime_get_sync() cannot really be blindly
modified without context and knowledge of each driver.

Pierre-Louis Bossart (11):

[PATCH 10/11] ASoC: tas2552: use pm_runtime_resume_and_get()

[Pierre-Louis Bossart]

The use of pm_runtime_get_sync() is buggy with no use of put_noidle() on
error.

Use pm_runtime_resume_and_get() instead.

Re: [PATCH 03/11] ASoC: soc-component: use pm_runtime_resume_and_get()

This patch turns out to be incorrect and should not be merged.

I missed the fact that the component pm_runtime_put() will decrease the
reference count that is already decreased with
pm_runtime_resume_and_get() when pm_runtime is not enabled. This leads
to warnings:

snd-soc-dummy snd-soc-dummy: Runtime PM usage count underflow!

Unfortunately we missed those warnings during validation, that's not so
good.

pm_runtime_resume_and_get() really needs to be used ONLY when the
get/put are part of the same function and the reference count can be
checked. When the get/put are in different functions, it's asking for
trouble.

Also the check on -EACCES is problematic when the component is handled
by a framework, it's not clear if that can happen or not.

The rest of the patches follow the pattern get_sync/put and don't have a
problem.

Sorry for the noise.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
