The check_req() helper uses pci_get_pdn() to get an OF node pointer. pci_get_pdn() returns a pci_dn pointer which either: 1) from the OF node returned by pci_device_to_OF_node(); 2) from the parent child_list where entries don't have OF node pointers. Since check_req() does not care about 2), it can call pci_device_to_OF_node() directly, hence the change. The find_pe_dn() helper uses embedded pci_dn to get an OF node which is also stored in edev->pdev so let's take a shortcut and call pci_device_to_OF_node() directly. With these 2 changes, we can finally get rid of the OF node back pointer. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> |

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.
