Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes from Thomas Glexiner:
- unbreak the irq trigger type check for legacy platforms
- a handful fixes for ARM GIC v3/4 interrupt controllers
- a few trivial fixes all over the place
* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
genirq/matrix: Make - vs ?: Precedence explicit
irqchip/imgpdc: Use resource_size function on resource object
irqchip/qcom: Fix u32 comparison with value less than zero
irqchip/exiu: Fix return value check in exiu_init()
irqchip/gic-v3-its: Remove artificial dependency on PCI
irqchip/gic-v4: Add forward definition of struct irq_domain_ops
irqchip/gic-v3: pr_err() strings should end with newlines
irqchip/s3c24xx: pr_err() strings should end with newlines
irqchip/gic-v3: Fix ppi-partitions lookup
irqchip/gic-v4: Clear IRQ_DISABLE_UNLAZY again if mapping fails
genirq: Track whether the trigger type has been set
