This prevents adding an irq_domain to a irq descriptor when irq_data exists, which true when the irq descriptor exists. This went unnoticed so far as the simple domain code did not enter this code path because domain->nr_irqs is always 0 for the simple domains. Split the check for irq_data == NULL out and have a separate warning for it.
