From 7eb776c42e75d17bd8107a1359068d8c742639d1 Mon Sep 17 00:00:00 2001 From: Kenji Kaneshige Date: Wed, 11 Nov 2009 14:35:22 +0900 Subject: [PATCH] PCI: introduce pci_is_pcie() Introduce pci_is_pcie() which returns true if the specified PCI device is PCI Express capable, false otherwise. The purpose of pci_is_pcie() is removing 'is_pcie' flag in the struct pci_dev, which is not needed because we can check it using 'pcie_cap' field. To remove 'is_pcie', we need to update user of 'is_pcie' to use pci_is_pcie() instead first.
