Subject: [PATCH] crypto: chacha_generic - remove unnecessary setkey() functions
Date: Sun, 17 Nov 2019 23:21:29 -0800	[thread overview]
Message-ID: <20191118072129.467514-1-ebiggers@kernel.org> (raw)

From: Eric Biggers <ebiggers@google.com>

Use chacha20_setkey() and chacha12_setkey() from
<crypto/internal/chacha.h> instead of defining them again in
chacha_generic.c.
