BugLink: https://bugs.launchpad.net/bugs/2064724

This reverts commit cf6889bb8b56d15f15d9b8e47ccab7b3b4c74bd6 which is
commit 27016f75f5ed47e2d8e0ca75a8ff1f40bc1a5e27 upstream.

It is reported to cause problems in older kernels due to some crypto
drivers having the same name, so revert it here to fix the problems.
