853a33ce69 irqchip: gic-v2m: Add support for ARM GICv2m MSI(-X) doorbell
Introduced a series of warnings when building ARM multi_v7_defconfig:
include/linux/irqchip/arm-gic.h:109:53: warning: its scope is only this definition or declaration, which is probably not what you want
In file included from arch/arm/mach-ux500/pm.c:13:0:
include/linux/irqchip/arm-gic.h:109:53: warning: 'struct irq_domain' declared inside parameter list
int gicv2m_of_init(struct device_node *node, struct irq_domain *parent);
^
Fix this by adding the proper include.
