> rzg3s_pcie_init_irqdomain() installs the chained INTx handlers before
> creating the INTx IRQ domain. irq_set_chained_handler_and_data() also
> enables the interrupt, so an INTx interrupt arriving in between is
> handled by rzg3s_pcie_intx_irq_handler() while host->intx_domain is
> still NULL, leading to a NULL pointer dereference.

> Move the IRQ domain creation before the loop that installs the chained
