The function s3c24xx_irq_map in arch/arm/mach-s3c24xx/irq.c contains the code: parent_irq_data = &parent_intc->irqs[irq_data->parent_irq]; if (!irq_data) { pr_err("irq-s3c24xx: no irq data found for hwirq %lu\n", hw); goto err; } At this point irq_data has already been tested, so the null test on irq_data does not look correct. But I wonder if parent_irq_data could ever be null here? julia -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
