- *  UWB radio controller:
- *
- *    1. alloc a uwb_rc, zero it
- *    2. call uwb_rc_init() on it to set it up + ops (won't do any
- *       kind of allocation)
- *    3. register (now it is owned by the UWB stack--deregister before
- *       freeing/destroying).
- *    4. It lives on it's own now (UWB stack handles)--when it
- *       disconnects, call unregister()
- *    5. free it.
- *
- *    Make sure you have a reference to the uwb_rc before calling
- *    any of the UWB API functions.
- *
- * TODO:
- *
- * 1. Locking and life cycle management is crappy still. All entry
- *    points to the UWB HCD API assume you have a reference on the
- *    uwb_rc structure and that it won't go away. They mutex lock it
- *    before doing anything.
