The function mce_severity() is not required to update its msg argument. In fact, mce_severity_amd() does not, which makes mce_no_way_out() return uninitialized data, which may be used later for printing. Assuming that implementations of mce_severity() either always or never update the msg argument (which is currently the case), it is sufficient to initialize the temporary variable in mce_no_way_out(). While at it, avoid printing a useless "Unknown". Signed-off-by: Jan H.

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.
