  "message": "PCI: Make pci_msi_setup_pci_dev() non-static for use by arch code\n\nCommit 1851617cd2da (\"PCI/MSI: Disable MSI at enumeration even if kernel\ndoesn\u0027t support MSI\") changed the location of the code that initialises\ndev-\u003emsi_cap/msix_cap and then disables MSI/MSI-X interrupts at PCI\nprobe time in devices that have this flag set. It moved the code from\npci_msi_init_pci_dev() to a new function named pci_msi_setup_pci_dev(),\ncalled by pci_setup_device().\n\nThe pseries PCI probing code does not call pci_setup_device(), so since\nthe aforementioned commit the function pci_msi_setup_pci_dev() is not\ncalled and MSI/MSI-X interrupts are left enabled. Additionally because\ndev-\u003emsi_cap/msix_cap are not initialised no driver can ever enable\nMSI/MSI-X.\n\nTo fix this, the pseries PCI probe should manually call\npci_msi_setup_pci_dev(), so this patch makes it non-static.\n\nFixes: 1851617cd2da (\"PCI/MSI: Disable MSI at enumeration even if kernel doesn\u0027t support MSI\")\n[mpe: Update change log to mention dev-\u003emsi_cap/msix_cap]\nSigned-off-by: Guilherme G.
