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 where a default domain actually exists.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
