Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq update from Thomas Gleixner: "A small set of updats/fixes for the irq subsystem: - Allow GICv3 interrupts to be configured as wake-up sources to enable wakeup from suspend - Make the error handling of the STM32 irqchip init function work - A set of small cleanups and improvements" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: irqchip/gic-v3: Allow interrupt to be configured as wake-up sources irqchip/tango: Set irq handler and data in one go dt-bindings: irqchip: renesas-irqc: Document r8a774a1 support irqchip/s3c24xx: Remove unneeded comparison of unsigned long to 0 irqchip/stm32: Fix init error handling irqchip/bcm7038-l1: Hide cpu offline callback when building for !SMP
