I would leave this function returning name directly and not whole struct characteristic_info.
Why ? We have this struct with characteristic information (maybe later
we'll add more information. Why limit ourselves to name only ?

If you plan to add more data into that structure then it is OK to return whole struct.
But if only name is to be used, then I would just call that function get_name() and
return name.

For now, i believe this is the only information we have for the
characteristic. I will send an updated patch.
