You can use a synchronous workqueue for setup and disconnect. This makes
sure the setup request and disconnect are executed in the same order as
it was seen by the UDC. So you enqueue the setup packet followed by the
disconnect. First you process the setup packet after that notify the
disconnect and put your udc into suspend.
How udc knows the disconnect has finished? suspend need to be called by udc.
Well, if you enqueue worker item and call in process context disconnect
of the gadget then you know when it is done once the function returns.
