Commit 71066545b48e ("driver core: Set fw_devlink.strict=1 by default")
enabled iommus and dmas dependency enforcement by default. On some
systems, this caused the console device's probe to get delayed until the
deferred_probe_timeout expires.
We need consoles to work as soon as possible, so mark the console device
node with FWNODE_FLAG_BEST_EFFORT so that fw_delink knows not to delay
the probe of the console device for suppliers without drivers. The
driver can then make the decision on where it can probe without those
suppliers or defer its probe.

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.
