usb: dwc3: gadget: synchronize_irq dwc irq in suspend

agree your findings.

so it's better move the synchronize_irq() after the spin_unlock_irqrestore(). static int dwc3_suspend_common(struct dwc3 *dwc)

{
	unsigned long	flags;

	switch (dwc->dr_mode) {
	case USB_DR_MODE_PERIPHERAL:
	case USB_DR_MODE_OTG:
		spin_lock_irqsave(&dwc->lock, flags);
		dwc3_gadget_suspend(dwc);
		spin_unlock_irqrestore(&dwc->lock, flags);
		synchronize_irq()
