Russell Currey ee57f8bba8 powerpc/kexec: Fix build failure from uninitialised variable 
commit 83ee9f2376 upstream.

clang 14 won't build because ret is uninitialised and can be returned if
both prop and fdtprop are NULL.  Drop the ret variable and return an
error in that failure case.

README 

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.
