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).
