| Subject: [PATCH] crypto: lib/chacha20poly1305 - define empty module exit |
| function |
| |
| commit ac88c322d0f2917d41d13553c69e9d7f043c8b6f upstream. |
| |
| With no mod_exit function, users are unable to unload the module after |
| use. I'm not aware of any reason why module unloading should be |
| prohibited for this one, so this commit simply adds an empty exit |
| function. |
