Subject: [PATCH] lib/test_kmod: remove a NULL test
Date: Fri, 28 Feb 2020 12:24:52 +0300
Message-ID: <20200228092452.vwkhthsn77nrxdy6@kili.mountain> (raw)

The "info" pointer has already been dereferenced so checking here is
too late.  Fortunately, we never pass NULL pointers to the
test_kmod_put_module() function so the test can simply be removed.
