Hmm, I will try to remove it, I put it here because when call pci_create_root_bus(), I could only pass the pci_host_bridge_ops, don't need to provide the bus number, pci_scan_root_bus() may lack the bus number resource at that time. But I think fix it is not a hard job, I will rework it, thanks. > >> struct device dev; >> struct pci_bus *bus; /* root bus */ >> struct list_head windows; /* resource_entry */ >> -- >> 1.7.1 >> > > . > -- Thanks!
