Dropping the lock before complete() is exactly the right thing to do.

Good, just as Alan said too.

But make sure your ep_queue() method understands that sometimes it's
only supposed to *queue* and not activate tx/rx.

Yes, I understand. A kind of atomic count, on all methods called from gadget,
which prevents reentrance (ie. no chains queue()->...->complete()->queue()).

As I have a bit of luck, all transfers are triggered through handle_ep(), which
if not called won't trigger any rx/tx (if counter was incremented).

Thanks for the info.
