Subject: [PATCH v4 1/6] lib/test_printf: Add empty module_exit function
In-Reply-To: <20190405015859.32755-1-tobin@kernel.org>
References: <20190405015859.32755-1-tobin@kernel.org>
Message-ID: <20190405015859.32755-2-tobin@kernel.org>

Currently the test_printf module does not have an exit function, this
prevents the module from being unloaded.  If we cannot unload the
module we cannot run the tests a second time.

Add an empty exit function.
