If none of irq category bits were set mpc52xx_get_irq() would pass NO_IRQ_IGNORE (-1) to irq_linear_revmap, which does an unsigned compare and declares the interrupt above the linear map range. It then punts to irq_find_mapping, which performs a linear search of all irqs, which will likely miss and only then return NO_IRQ. If no status bit is set, then we should return NO_IRQ directly. The interrupt should not be suppressed from spurious counting, in fact that is the definition of supurious.
