[PATCH 9/9] radeon: use pdev->pm_cap instead of pci_find_capability(..,PCI_CAP_ID_PM)

From: Yijing Wang
Date: Tue Jun 18 2013 - 04:25:56 EST


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.
