I squashed this into the original fix with your S-o-b, and Will's Ack.
Pushing to irqchip/for-next shortly.

thx,

    irqchip: gic: Remove warning by including linux/irqdomain.h
    
    Commit
    
      853a33ce6932 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.
