Wow, that is amazing!

Thanks a lot for doing all of this work.  In the end, you saved a lot of
memory dropping that lock in the urb, and hopefully we can clean up all
of the drivers so that it is much harder for developers to do things
wrong in the future.

Now I'll work on dropping the ->status usage from the remaining USB
drivers, before we change the urb callback function.  That might be
something I can do while traveling in the next few weeks...

thanks again for doing this.
