NAME
       handle_level_irq - Level type irq handler

SYNOPSIS
       void handle_level_irq(struct irq_desc * desc);

ARGUMENTS
       desc
           the interrupt description structure for this irq

DESCRIPTION
       Level type interrupts are active as long as the hardware line has the active level. This
       may require to mask the interrupt and unmask it after the associated handler has
       acknowledged the device, so the interrupt line is back to inactive.
