Subject: [PATCH v8 4/7] PCI: OF: Initialize dev->fwnode appropriately
Date: Thu, 30 May 2019 18:09:26 +0100
Message-ID: <20190530170929.19366-5-jean-philippe.brucker@arm.com> (raw)
In-Reply-To: <20190530170929.19366-1-jean-philippe.brucker@arm.com>

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").

Acked-by: Bjorn Helgaas <bhelgaas@google.com>
