The code introduced in "[PATCH kernel v12 17/34] powerpc/spapr: vfio: Switch from iommu_table to new iommu_table_group" checks that an IOMMU group was registered for the specific table group which is not true when CONFIG_IOMMU_API is off as iommu_register_group() is a stub in this case. This makes BUG_ON conditional. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> --- arch/powerpc/platforms/powernv/pci.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
