Bottomley Cc: [email protected]; Hanjun Guo; [email protected]; Yijing Wang; [email protected]; [email protected]; [email protected] Subject: [PATCH 8/9] 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.
