It might be better to print the name of the role here because I suspect
very few people know the value of the role defines without looking them
up. I thought there was already a function to return the role name for
a given enum usb_role, but it seems like we only have name -> enum
conversion. Might be worth adding that, but doesn't have to be as part
of this series.
