The device links used by rockchip-iommu and exynos-iommu are
completely managed by these drivers within the IOMMU framework,
so there is no reason to involve the driver core in the management
of these links.
For this reason, make rockchip-iommu and exynos-iommu pass
DL_FLAG_STATELESS in flags to device_link_add(), so that the device
links used by them are stateless.
[Note that this change is requisite for a subsequent one that will
rework the management of stateful device links in the driver core
and it will not be compatible with the two drivers in question any
more.]

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
