This flag can never be added to a device link that already exists and doesn't have the flag set. It can only be added when a device link is created for the first time or it can be maintained if the device link already has the it set. This flag will be used for marking device links created ONLY by inferring dependencies from data and NOT from explicit action by device drivers/frameworks. This will be useful in the future when we need to deal with cycles in dependencies inferred from firmware.

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.
