Sylvain Rochet bb0a203c3a usb: gadget: atmel_usba_udc: Request an auto disabled Vbus signal IRQ ... Vbus IRQ handler needs a started UDC driver to work because it uses udc->driver, which is set by the UDC start handler. The previous way chosen was to return from interrupt if udc->driver is NULL using a spinlock around the check. We now request an auto disabled (IRQ_NOAUTOEN) Vbus signal IRQ instead of an auto enabled IRQ followed by disable_irq(). This way we remove the very small timeslot of enabled IRQ which existed previously between request() and disable(). We don't need anymore to check if udc->driver is NULL in IRQ handler.
