[PATCH 2/9] amd8111e: use pdev->pm_cap instead of pci_find_capability(..,PCI_CAP_ID_PM)
From: Yijing Wang <hidden>
Date: 2013-06-18 08:07:22
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 <redacted> Cc: "David S.
