I don't understand what "for role is %d" means here. I think perhaps you
meant to simply say "for role %d"? Also, perhaps add parentheses after
the "%s" to clarify that you're referring to a function.

Yes, intention is to print role, Will update as mentioned "for role %d"
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.

Will add a structure to define strings for roles enums, similar to modes
usage in this driver.
