USB: twl6030-usb: pass IRQF_ONESHOT to request_threaded_irq
The flag of IRQF_ONESHOT should be passed to request_threaded_irq, otherwise the following failure message will be dumped because hardware handler is defined as NULL: [ 2.271148] genirq: Threaded irq requested with handler=NULL and !ONESHOT for irq 356 [ 2.279541] twl6030_usb twl6030_usb: can't get IRQ 356, err -22 [ 2.285919] twl6030_usb: probe of twl6030_usb failed with error -22 The patch fixes the twl6030-usb probe failure.
