Make a new op that receives the device and the mm_struct that the SVA domain should be created for. Unlike domain_alloc_paging() the dev argument is never NULL here. This allows drivers to fully initialize the SVA domain and allocate the mmu_notifier during allocation. It allows the notifier lifetime to follow the lifetime of the iommu_domain. Since we have only one call site, upgrade the new op to return ERR_PTR instead of NULL.

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 reStructuredText 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.
