These drivers do not use mac80211, which is a prerequisite for inclusion in the
regular wifi tree. A complete rewrite will be needed to get them out of staging.
Nonetheless, cleanups are in order.

The patches against rtl8188eu and rtl8712 are certainly OK. The patches against
rtl8192u are not so easily seen to be correct. In addition, I do not have this
hardware and I cannot test. In fact, I wonder if anyone is using this particular
hardware.

With the above qualification,

Thanks,

Larry
