With char becoming unsigned by default, and with `char` alone being ambiguous and based on architecture, we get a warning when assigning the unchecked output of hex_to_bin() to that unsigned char. Mark `key` as a `u8`, which matches the struct's type, and then check each call to hex_to_bin() before casting.

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.
