Since commit fcc392d501bd2 ("irqchip/armada-370-xp: Use the generic MSI infrastructure"), the irqchip driver used on Armada 370, XP, 375, 38x, 39x for the MPIC interrupt controller has been converted to use the generic MSI infrastructure. Since this commit, it is no longer registering an msi_controller structure with the of_pci_msi_chip_add() function. Therefore, having the PCI driver used on the same platform calling of_pci_find_msi_chip_by_node() is pretty useless. The MSI resolution is now done in the generic interrupt resolution code, since the MSI controller is an irq domain attached to the interrupt controller node, which is pointed to by the msi-parent DT property in the PCIe controller node.
