From 8986f223bd777a73119f5d593c15b4d630ff49bb Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 16 Nov 2020 13:52:47 +0100 Subject: [PATCH] iommu/vt-d: Take CONFIG_PCI_ATS into account pci_dev::physfn is only available when CONFIG_PCI_ATS is set. The recent fix for the irqdomain rework missed that dependency which makes the build fail when CONFIG_PCI_ATS=n. Add the necessary #ifdeffery.
