If\nirq_create_mapping() fails, port->intx_irq stays initialized.\n\nHence, remove the IRQ domains in the error path by calling\nplda_pcie_irq_domain_deinit().\n\nSince plda_pcie_irq_domain_deinit() now disposes of the intx_irq and\nmsi_irq mappings itself before removing their domains, the msi_irq\nmapping failure path can go directly to err_irq_domain_deinit instead of\ndisposing of port->intx_irq separately first.\n\nThis issue was found by automated review of sashiko-bot\n\n[mani: commit log]"
