From c8a2ba3f50f7445b3d1b822ba1a8168b4234baca Mon Sep 17 00:00:00 2001 From: Yijing Wang Date: Thu, 27 Jun 2013 15:02:49 +0800 Subject: [SCSI] pm8001: 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.
