[RFC PATCH v2 02/32] PCI: introduce pci_pcie_type(dev) to replace pci_dev->pcie_type

From: Jiang Liu
Date: Tue Jul 24 2012 - 12:33:33 EST

From: Yijing Wang <wangyijing@xxxxxxxxxx>

From: Yijing Wang <wangyijing@xxxxxxxxxx>

Introduce an inline function pci_pcie_type(dev) to extract PCIe
device type from pci_dev->pcie_flags_reg field, and prepare for
removing pci_dev->pcie_type.
