In the Linux kernel, the following vulnerability has been resolved:irqchip/riscv-aplic: Prevent crash when MSI domain is missingIf the APLIC driver is probed before the IMSIC driver, the parent MSIdomain will be missing, which causes a NULL pointer dereference inmsi_create_device_irq_domain().Avoid this by deferring probe until the parent MSI domain is available. Usedev_err_probe() to avoid printing an error message when returning-EPROBE_DEFER.
