This sets PCI_BUS_FLAGS_MSI_REMAP to a bus if MSI remapping is an IRQ domain is capable of MSI remapping. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> --- Changes: v4: * dropped pci_bus_msi_isolated() which looked for (never pushed out) MSI_FLAG_IRQ_REMAPPING; used irq_domain_hierarchical_is_msi_remap() instead --- drivers/pci/probe.c | 4 ++++ 1 file changed, 4 insertions(+)
