crypto: ccp - Silence strncpy warning
This patch kills an strncpy by using strscpy instead. The name would be silently truncated if it is too long. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Acked-by: John Allen <john.allen@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
