I suspect the old code is a deliberate attempt to indicate that it
the error value that is being returned rather than the pointer.
Looking higher up that file there seems to be a fubar when setting
up the TKIP key.
It seems to put the same 6 bytes into every TID.
(I'm sure seq_len shouldn't be ignored either.0
