With all due respect, you are not helping here but rather slowing things 
down. I've done dozens of cleanups in the ALSA tree and I didn't go in 
this sort of details. The fact that the series was tagged as Reviewed by 
Takashi on April 11 and we are still discussing trivial changes tells me 
the integration model is broken. It's not just me, the patches related 
to runtime-pm from your own Linaro colleagues posted on March 28 went 
nowhere either.

Moving forward, I suggest we merge SoundWire-related patches through the 
sound tree. There will be dependencies in the coming weeks between SOF 
and SoundWire and it makes no sense to have separate maintainers and 
make the life of early adopters more complicated than it needs to be. If 
we have 3-week delays for trivial stuff, I can't imagine what the pace 
will be when I publish the next 20-odd patches I am still working on, 
and the code needed for the SoundWire audio device class being 
standardized as we speak. Things were fine up to now since no one was 
actually using the code, we are in a different model now.
