Subject: [PATCH] crypto: tcrypt - do not attempt to write to readonly variable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit da7f033ddc9fdeb (â€crypto: cryptomgr - Add test infrastructureâ€) added a
const to variable which is later used as target buffer of memcpy.
crypto/tcrypt.c:217:12: warning: passing 'const char (*)[128]' to parameter of type 'void *' discards qualifiers
memset(&iv, 0xff, iv_len);
crypto/tcrypt.c:test_cipher_speed()
- unsigned char *key, iv[128];
+ const char *key, iv[128];
...
memset(&iv, 0xff, iv_len);
