Thanks for the feedback, will send a formal patch with the helper and 
machine driver changes after I test more with the legacy drivers. Do you 
have a preference for one patch that deals with multiple machines 
drivers in one shot, or individual patches? The latter are nicer for 
backports (e.g. for Chrome), the former nicer for maintainers...

The goal of reusing machine drivers as is isn't really achievable 
anyways, it looks like we are going to have additional changes, e.g. if 
we want to avoid the calls to snd_pcm_suspend as suggested by Takashi, 
we'll have to add a reference to snd_soc_pm_ops that's only used for 
SOF, the Atom/SST driver does things in different ways mostly due to 
historical reasons.
