    Subject[PATCH v10 1/2] mfd: madera: Add irqchip data pointer into struct madera
    Date
    Put the pointer to struct regmap_irq_chip_data into the parent
    mfd structure so that the child irqchip driver does not need
    a trivial private structure to store only this pointer. As
    the irqchip child driver already has a pointer to the parent
    struct madera it can use that to store the pointer. This also
    means that the irqchip driver does not need a double-indirection
    from its local struct to get at the parent struct madera.
