[ Upstream commit3a2dbc510c] When a device X is bound successfully to a driver, if it has a child firmware node Y that doesn't have a struct device created by then, we delete fwnode links where the child firmware node Y is the supplier. We did this to avoid blocking the consumers of the child firmware node Y from deferring probe indefinitely. While that a step in the right direction, it's better to make the consumers of the child firmware node Y to be consumers of the device X because device X is probably implementing whatever functionality is represented by child firmware node Y. By doing this, we capture the device dependencies more accurately and ensure better probe/suspend/resume ordering.

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.
