Subject: [PATCH v2 2/6] crypto: stm32/hash: Simplify code
Date: Tue, 10 Jan 2023 20:19:13 +0100	[thread overview]
Message-ID: <20221227-ux500-stm32-hash-v2-2-bc443bc44ca4@linaro.org> (raw)
In-Reply-To: <20221227-ux500-stm32-hash-v2-0-bc443bc44ca4@linaro.org>

We are passing (rctx->flags & HASH_FLAGS_FINUP) as indicator
for the final request but we already know this to be true since
we are in the (final) arm of an if-statement set from the same
flag. Just open-code it as true.

Acked-by: Lionel Debieve <lionel.debieve@foss.st.com>
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
