xilinx_pl_dma_pcie_init_irq_domain() takes a reference to the PCIe interrupt-controller child node with of_get_child_by_name(), but the error paths after the two irq_domain_create_linear() calls and after xilinx_pl_dma_pcie_init_msi_irq_domain() return directly without dropping it. irq_domain_create_linear() gets its own reference on the fwnode, so the domains do not consume the caller's one. Add an err_put_node label that drops the reference before returning.
