+/**

+ * @udc: The UDC which should disable async callbacks
+ *
+ * This routine is used when unbinding gadget drivers.  It prevents a race:
+ * The UDC driver doesn't know when the gadget driver's ->unbind callback
+ * runs, so unless it is told to disable asynchronous callbacks, it might
+ * issue a callback (such as ->disconnect) after the unbind has completed.
+ *
+ * After this function runs, the UDC driver must suppress all ->suspend,
+ * ->resume, ->disconnect, ->reset, and ->setup callbacks to the gadget driver
+ * until async callbacks are again enabled.  A simple-minded but effective
+ * way to accomplish this is to tell the UDC hardware not to generate any
+ * more IRQs.
+ *
+ * Request completion callbacks must still be issued.  However, it's okay
+ * to defer them until the request is cancelled, since the pull-up will be
+ * turned off during the time period when async callbacks are disabled.

+ * This routine will always be called in process context.
