From 59b099a6c75e4ddceeaf9676422d8d91d0049755 Mon Sep 17 00:00:00 2001 From: Jean-Philippe Brucker Date: Tue, 15 Jan 2019 12:19:56 +0000 Subject: [PATCH] PCI: OF: Initialize dev->fwnode appropriately For PCI devices that have an OF node, set the fwnode as well. This way drivers that rely on fwnode don't need the special case described by commit f94277af03ea ("of/platform: Initialise dev->fwnode appropriately").
