Is this implementation detail worth for further considerations?

I assume you are referring to the allocation of devpriv->ai_urbs and devpriv->ao_urbs? Your patch does not reduce their sizes; `urb` and `*devpriv->ai_urbs` have the same type `struct urb *`. Having said that, `sizeof(*devpriv->ai_urbs)` is cleaner code than `sizeof(urb)` in this case.
