Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq fixes from Thomas Gleixner:
 "The last two one-liners for 4.3 from the irqchip space:

   - Regression fix for armada SoC which addresses the fallout from the
     set_irq_flags() cleanup

   - Add the missing propagation of the irq_set_type() callback to the
     parent interrupt controller of the tegra interrupt chip"

* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  irqchip/tegra: Propagate IRQ type setting to parent
  irqchip/armada-370-xp: Fix regression by clearing IRQ_NOAUTOEN
