[PATCH] ASoC: SOF: using pm_runtime_resume_and_get to simplify the code

[cgel.zte]

From: Minghao Chi <chi.minghao@zte.com.cn>

Using pm_runtime_resume_and_get() to replace pm_runtime_get_sync and
pm_runtime_put_noidle. This change is just to simplify the code, no
actual functional changes.

Well, maybe that's a simplification, but we've been using the same pattern for years now.

Is there really a clear direction to use this new function?

the overwhelming majority of drivers in sound/soc still rely on the pm_runtime_get_sync (111 v. 7).

It seems like a much better pattern and there's been a steady stream of
conversion patches.  The whole get/idle thing is pretty much just sharp
edges.

We'll get there I'm sure.

ok, I'll send follow-up patches for the remaining code.

Thanks!

[1/1] ASoC: SOF: using pm_runtime_resume_and_get to simplify the code
      commit: b3598fe6d009b2f2144115dfc381615c8b534aec

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
