Subject: [PATCH v3 1/7] lib/test_printf: Add empty module_exit function
Date:   Thu,  7 Mar 2019 08:42:20 +1100
Message-Id: <20190306214226.14598-2-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.
