Subject: [PATCH v2 02/11] crypto: blake2b - define shash_alg structs using macros
Date: Thu, 17 Dec 2020 14:21:29 -0800 [thread overview]
Message-ID: <20201217222138.170526-3-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 BLAKE2b are identical
except for the algorithm name, driver name, and digest size. So, avoid
code duplication by using a macro to define these structs.
