[PATCH v2 12/33] iommu: Move iommu_group_create_direct_mappings() out of iommu_group_add_device()
From: Joerg Roedel <jroedel at suse.de>
After the previous changes the iommu group may not have a default
domain when iommu_group_add_device() is called. With no default domain
iommu_group_create_direct_mappings() will do nothing and no direct
mappings will be created.
Rename iommu_group_create_direct_mappings() to
iommu_create_device_direct_mappings() to better reflect that the
function creates direct mappings only for one device and not for all
devices in the group. Then move the call to the places...
