From 94973b24d61b03f99017f836d85e7d6739741bab Mon Sep 17 00:00:00 2001 From: Alistair Popple Date: Thu, 17 Dec 2015 13:43:11 +1100 Subject: [PATCH] Revert "powerpc/pci: Remove unused struct pci_dn.pcidev field" This commit removed the pcidev field from struct pci_dn as it was no longer in use by the kernel. However to support finding the association of Nvlink devices to GPU devices from the device-tree this field is required. This reverts commit 250c7b277c65 ("powerpc/pci: Remove unused struct pci_dn.pcidev field").
