From 29150078d7a1758df8c7a6cd2ec066ac65e1fab9 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Tue, 9 Jun 2009 10:54:18 +0200 Subject: [PATCH] amd-iommu: remove BUS_NOTIFY_BOUND_DRIVER handling Handling this event causes device assignment in KVM to fail because the device gets re-attached as soon as the pci-stub registers as the driver for the device.
