[CRYPTO] tcrypt: Return -EAGAIN from module_init()
Michal Ludvig [Tue, 30 May 2006 04:49:38 +0000 (14:49 +1000)]
Intentionaly return -EAGAIN from module_init() to ensure
it doesn't stay loaded in the kernel.  The module does all
its work from init() and doesn't offer any runtime
functionality => we don't need it in the memory, do we?
