Subject: [PATCH 04/29] crypto: skcipher - remove redundant check for SKCIPHER_WALK_SLOW
Date: Sat, 21 Dec 2024 01:10:31 -0800 [thread overview]
Message-ID: <20241221091056.282098-5-ebiggers@kernel.org> (raw)
In-Reply-To: <20241221091056.282098-1-ebiggers@kernel.org>
From: Eric Biggers <ebiggers@google.com>
In skcipher_walk_done(), remove the check for SKCIPHER_WALK_SLOW because
it is always true. All other flags (and lack thereof) were checked
earlier in the function, leaving SKCIPHER_WALK_SLOW as the only
remaining possibility.
