crypto: tcrypt - do not attempt to write to readonly variable
Commit da7f033ddc9fdeb (”crypto: cryptomgr - Add test infrastructure”) 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);
