[Thomas Gleixner <tglx@linutronix.de>]

Linus,

please pull the latest irq/urgent branch from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-urgent-2021-03-14

up to:  b470ebc9e0e5: Merge tag 'irqchip-fixes-5.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent


A set of irqchip updates:

  - Make the GENERIC_IRQ_MULTI_HANDLER configuration correct

  - Add a missing DT compatible string fir tge Ingenic driver

  - Remove the pointless debugfs_file pointer from struct irqdomain

Thanks,

	tglx
