Subject: [PATCH] cifs: Fix crash on unload of cifs_arc4.ko
The exit function is wrongly placed in the __init section and this leads
to a crash when the module is unloaded. Just remove both the init and
exit functions since this module does not need them.
Fixes: 71c02863246167b3d ("cifs: fork arc4 and create a separate module...")
