Good point, I thought it wouldn't matter but it does. I just gave it a 
try and there seems to be a conflict on Mark's tree w/ 
drivers/soundwire/intel.c (likely due to missing patches already added 
to Vinod's tree).

So this should go to Vinod's tree with Mark's Acked-by tag on the ASoC 
changes.

Alternatively we can also split this in two, with ASoC-only and 
SoundWire-only patches in separate series if it's easier for 
maintainers. We would lose the rationale for the changes but that's not 
essential.

Right. if you are fine with the content and this goes in your tree, can 
this be modified while applying? Or do want a v2?
