Merge tag 'irq-fixes-4.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip/irqdomain updates for 4.11-rc2 from Marc Zyngier - irqchip/crossbar: Some type tidying up - irqchip/gicv3-its: Workaround for a Qualcomm erratum - irqdomain: Compile for for systems that don't use CONFIG_IRQ_DOMAIN Fixed up minor conflict in the crossbar driver.
