From ff45ab96465f013bee39ac88b756bb1129a7bc9d Mon Sep 17 00:00:00 2001 From: Tina Zhang Date: Thu, 13 Apr 2023 12:06:44 +0800 Subject: iommu/vt-d: Remove a useless BUG_ON(dev->is_virtfn) When dmar_alloc_pci_notify_info() is being invoked, the invoker has ensured the dev->is_virtfn is false. So, remove the useless BUG_ON in dmar_alloc_pci_notify_info().
