From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx> pcie-altera-msi.c uses irq_domain_add_linear() and related interfaces, so it needs <linux/irqdomain.h> but doesn't include it directly; it relies on the fact that <linux/of_irq.h> includes it. But pcie-altera-msi.c *doesn't* need <linux/of_irq.h> itself. Include <linux/irqdomain.h> directly to remove this implicit dependency so a future patch can drop <linux/of_irq.h>.
