This code does: spin_unlock_irq(&udc->ud.lock); spin_unlock_irqrestore(&udc->lock, flags); which does not make sense. In theory, the first unlock could enable IRQs and then the second _irqrestore could disable them again. There would be a brief momemt where IRQs were enabled improperly. In real life, however, this function is always called with IRQs enabled and the bug does not affect runtime.
