First of all, if a variable is not used, then it should be removed, not merely 
renamed to satisfy checkpatch.

All the Realtek USB devices should be added to rtl8xxxu, not merely moved into 
that directory. Jes Sorensen created a well-designed driver the is structured to 
permit addition of different initialization routines, etc. That said, the 
conversion will not be easy. In addition, it will require having your hands on a 
real device - a requirement that I cannot meet for the RTL8192U.
