Subject: [PATCH 2/2] crypto: caam - Remove messages related to memory allocation failure
Date:   Sat, 22 Jul 2023 16:53:59 +0200
Message-Id: <b8859de12248852f661cb051ffad79166e8dfa47.1690037578.git.christophe.jaillet@wanadoo.fr>
In-Reply-To: <0fc02b533bd3c3422bec5856bc65bbb66ebf7b58.1690037578.git.christophe.jaillet@wanadoo.fr>

Precedence: bulk

On memory allocation failure, the function calling stack is already logged.
So there is no need to explicitly log an extra message.

Remove them, ans simplify some code accordingly.
