Yes it's for Chrome OS UCM config only.

I agree that it's make more sense to have a unique driver name but that 
may require some additional code changes to identify hardware config and 
machine driver changes for sound card registration based on components.
I'll surely look into this and try to refine our machine driver code in
near future but it would be nice if we merge this for now. We will 
upload new patch series soon to support unique naming.
