Merge tag 'irq-urgent-2021-03-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes from Thomas Gleixner: "A set of irqchip updates: - Make the GENERIC_IRQ_MULTI_HANDLER configuration correct - Add a missing DT compatible string for the Ingenic driver - Remove the pointless debugfs_file pointer from struct irqdomain" * tag 'irq-urgent-2021-03-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: irqchip/ingenic: Add support for the JZ4760 dt-bindings/irq: Add compatible string for the JZ4760B irqchip: Do not blindly select CONFIG_GENERIC_IRQ_MULTI_HANDLER ARM: ep93xx: Select GENERIC_IRQ_MULTI_HANDLER directly irqdomain: Remove debugfs_file from struct irq_domain
