PCI: plda: Fix IRQ domain leaks in the error paths of plda_init_interrupts()
In the Linux kernel, the following vulnerability has been resolved: PCI: plda: Fix IRQ domain leaks in the error paths of plda_init_interrupts() plda_init_interrupts() initializes IRQ domains and creates IRQ mapping but does not unwind them when later step fails. If platform_get_irq() or either irq_create_mapping() fails in plda_init_interrupts(), the domains are never deinitialized. If irq_create_mapping() fails, port->intx_irq stays initialized. Hence, remove the IRQ domains in the error path by calling plda_pcie_irq_domain_deinit(). Since plda_pcie_irq_domain_deinit() now disposes of the intx_irq and msi_irq mappings itself before removing their domains, the msi_irq mapping failure path can go directly to err_irq_domain_deinit instead of disposing of port->intx_irq separately first. This issue was found by automated review of sashiko-bot [mani: commit log]
