Until now, legacy WMI notify handler functions where using the wmi_block_list, which did no refcounting on the returned WMI device. This meant that the WMI device could disappear at any moment, potentially leading to various errors. Fix this by using bus_find_device() which returns an actual reference to the found WMI device. Tested on a Dell Inspiron 3505 and a Acer Aspire E1-731.

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.
