Many aggregate WMI drivers do not use -EPROBE_DEFER when they cannot find a WMI device during probe, instead they require all WMI devices associated with an platform device to become available at once. This is currently achieved by adding those WMI devices to the wmi_block_list before they are registered, which is then used by the deprecated GUID-based functions to search for WMI devices. Replace this approach with a device link which defers probing of the WMI device until the associated platform device has finished probing (and has registered all WMI devices). New aggregate WMI drivers should not rely on this behaviour.

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.
