Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes from Thomas Gleixner: "A few minor fixlets in ARM SoC irq drivers and a fix for a memory leak which I introduced in the last round of cleanups :(" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq: Fix memory leak when calling irq_free_hwirqs() irqchip: spear_shirq: Fix interrupt offset irqchip: brcmstb-l2: Level-2 interrupts are edge sensitive irqchip: armada-370-xp: Mask all interrupts during initialization.
