Subject: [PATCH] crypto: Redundant type conversion for AES_KEY pointer
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
We can delete the redundant type conversion if
we set the the AES_KEY parameter with 'const' in
qcrypto_cipher_aes_ecb_(en|de)crypt() function.
