bdc_ep_disable() expects to be called with bdc->lock held. The assumption is met in all the cases except for call from bdc_udc_exit(), that is called from bdc_remove(). As a result a race can happen or unheld bdc->lock can be unlocked in bdc_req_complete(). The patch proposes to acquire-release bdc->lock around bdc_ep_disable() in bdc_udc_exit().
