From d08d6f5d75242ceb410efbdf650efecc40d68c2d Mon Sep 17 00:00:00 2001 From: Pierre Morel Date: Fri, 21 Feb 2020 17:20:46 +0100 Subject: s390/pci: adaptation of iommu to multifunction In the future the bus sysdata may not directly point to the zpci_dev. In preparation of upcoming patches let us abstract the access to the zpci_dev from the device inside the pci device.
