Daniel Wagner 0a29ac5bd3 net: usb: lan78xx: Disable interrupts before calling generic_handle_irq() 
lan78xx_status() will run with interrupts enabled due to the change in
ed194d1367 ("usb: core: remove local_irq_save() around ->complete()
handler"). generic_handle_irq() expects to be run with IRQs disabled.
