I lost the original mail from Duc, but I applied this to pci/host-xgene for
v4.4 with this changelog:

commit 00b9b91cb330e70b6bc571a9aa7175b4590ca452
Author: Duc Dang <dhdang@apm.com>

    PCI/MSI: xgene: Remove msi_controller assignment
    
    After 8d63bc7beaee ("PCI/MSI: pci-xgene-msi: Get rid of struct
    msi_controller"), it is no longer required to assign msi_controller for
    X-Gene PCIe host bridge to support MSI.
    
    Remove this unnecessary code.  This also avoids a warning message ("failed
    to enable MSI") during boot.
