Michal Wajdeczko bc9b9c5026 kunit: Reset test->priv after each param iteration 
[ Upstream commit 342fb97892 ]

If we run parameterized test that uses test->priv to prepare some
custom data, then value of test->priv will leak to the next param
iteration and may be unexpected.  This could be easily seen if
we promote example_priv_test to parameterized test as then only
first test iteration will be successful:

$ ./tools/testing/kunit/kunit.py run \
	--kunitconfig ./lib/kunit/.kunitconfig *.example_priv*

Fix that by resetting test->priv after each param iteration, in
similar way what we did for the test->status.

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.
