-Subject: [PATCH] crypto: chacha - unexport chacha_generic routines
-
-commit 22cf705360707ced15f9fe5423938f313c7df536 upstream.
-
-Now that all users of generic ChaCha code have moved to the core library,
-there is no longer a need for the generic ChaCha skcpiher driver to
-export parts of it implementation for reuse by other drivers. So drop
-the exports, and make the symbols static.
