Richard Fitzgerald 1bddcf77ce kunit: test: Avoid cast warning when adding kfree() as an action
In kunit_log_test() pass the kfree_wrapper() function to kunit_add_action()
instead of directly passing kfree().

This prevents a cast warning:

lib/kunit/kunit-test.c:565:25: warning: cast from 'void (*)(const void *)'
to 'kunit_action_t *' (aka 'void (*)(void *)') converts to incompatible
function type [-Wcast-function-type-strict]

   564		full_log = string_stream_get_string(test->log);
 > 565		kunit_add_action(test, (kunit_action_t *)kfree, full_log);

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.
