From f9c7da5eaf10fa1d7a91b83aefc6fb8e3a4ad39c Mon Sep 17 00:00:00 2001 From: Yijing Wang Date: Tue, 18 Jun 2013 16:06:37 +0800 Subject: [PATCH] amd8111e: use pdev->pm_cap instead of pci_find_capability(.., PCI_CAP_ID_PM) Pci core has been saved pm cap register offset by pdev->pm_cap in pci_pm_init() in init path. So we can use pdev->pm_cap instead of using pci_find_capability(pdev, PCI_CAP_ID_PM) for better performance and simplified code. Signed-off-by: Yijing Wang Cc: "David S.
