Well, not really. The call to iommu_alloc_default_domain() in iommu_group_get_for_dev() has to stay around as long as there are IOMMU drivers using the add/remove_device() call-backs instead of probe/release_device(). Those drivers expect that iommu_group_get_for_dev() returns the device attached to a group and the group set up with a default domain (and the device attached to the groups current domain). But when all drivers are converted this compatability mess can be removed.

README
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.
