Revision 0774e392555a128cff7a94929b9ce957927fef49 authored by Joerg Roedel on 28 September 2012, 14:14:44 UTC, committed by Joerg Roedel on 28 September 2012, 14:14:44 UTC
The new IOMMU groups code in the AMD IOMMU driver makes the assumption that there is a pci_dev struct available for all device-ids listed in the IVRS ACPI table. Unfortunatly this assumption is not true and so this code causes a NULL pointer dereference at boot on some systems. Fix it by making sure the given pointer is never NULL when passed to the group specific code. The real fix is larger and will be queued for v3.7.
