You understood correctly, it took me time to understand :-)
No problem I can split this patch:

> > +     select REGMAP_SPI if SPI_MASTER

It will go to  v4 mfd: mc13xxx-core: use regmap for register access, 

Only the second part will be in this patch

-	struct device_node *np = mc13xxx->dev.of_node;
+	struct device_node *np = mc13xxx->dev->of_node;
