For a PCI device it's pci_dn can be retrieved from pdev->dev.archdata.firmware_data, PCI_DN(devnode), or parent's list. Thus, we should just use the existing function pci_get_pdn_by_devfn to get the pci_dn. Signed-off-by: Bryant G.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
