+1

The prefix of sound bindings is quite unique from other subsystems.
Looking at the prefix of Documentation/devicetree/bindings/sound/
commits, I'm always confused whether it's a pure binding commit
or just submitted as part of the driver patch.  I feel that we
kinda lose the point of having a prefix.

Just my 2 cents.
