Subject: [PATCH 9/9] radeon: use pdev->pm_cap instead of pci_find_capability(..,PCI_CAP_ID_PM)
Date: Wed, 26 Jun 2013 01:13:41 +0000 [thread overview]
Message-ID: <1372209221-16492-1-git-send-email-wangyijing@huawei.com> (raw)
In-Reply-To: <1371543891-11460-1-git-send-email-wangyijing@huawei.com>
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.
