Date: Thu, 30 May 2013 13:45:34 +0800 From: Xudong Hao <xudong.hao@...el.com> To: bhelgaas@...gle.com Cc: yinghai@...nel.org, linux-pci@...r.kernel.org, linux-kernel@...r.kernel.org, Xudong Hao <xudong.hao@...el.com> Subject: [PATCH] PCI: set correct value for iov device before device Since device registering is put into pci_device_add(), it must set value of Virtual Function device's member before the pci_dev is put to device tree. Or some relevant subsystem of driver model such as xen will report a incorrect IOV device to Xen hypervior.
