Subject: [PATCH v2 06/11] crypto: blake2s - define shash_alg structs using macros
Date: Thu, 17 Dec 2020 14:21:33 -0800	[thread overview]
Message-ID: <20201217222138.170526-7-ebiggers@kernel.org> (raw)
In-Reply-To: <20201217222138.170526-1-ebiggers@kernel.org>

From: Eric Biggers <ebiggers@google.com>

The shash_alg structs for the four variants of BLAKE2s are identical
except for the algorithm name, driver name, and digest size.  So, avoid
code duplication by using a macro to define these structs.
