I'd rather use dev_name() for the CODEC itself if possible, that is more
likely to be stable going forward and one of the immediate aims with the
API refactoring is to remove socdev entirely at runtime.

That can be done in a followup, though.

but this doesn't seem to accomplish that goal?  I can't actually spot
the difference either, I'm assuming it's just whitespace?  If so I'll
apply as-is.
