Merge tag 'irqchip-4.15-4' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip updates for 4.15, take #4 from Marc Zyngier
- A core irq fix for legacy cases where the irq trigger is not reported
by firmware
- A couple of GICv3/4 fixes (Kconfig, of-node refcount, error handling)
- Trivial pr_err fixes
