Merge tag 'irq-urgent-2022-02-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes from Thomas Gleixner: "Interrupt chip driver fixes: - Don't install an hotplug notifier for GICV3-ITS on systems which do not need it to prevent a warning in the notifier about inconsistent state - Add the missing device tree matching for the T-HEAD PLIC variant so the related SoC is properly supported" * tag 'irq-urgent-2022-02-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: irqchip/sifive-plic: Add missing thead,c900-plic match string dt-bindings: update riscv plic compatible string irqchip/gic-v3-its: Skip HP notifier when no ITS is registered
