So the issue isn't that the driver doesn't have a name, it's that you
don't like the name it was given.  The changelog needs to explain this,

This sounds like you should fix userspace.  It does go back to the issue
I regularly raise with the Blackfin code constantly assuming that there
can be a single driver which covers all combinations of a Blackfin CPU
with a given CODEC.
