OpenSSL SSL_CTX_set_tmp_dh memory leak

I need some clarification on this example taken from the OpenSSL documentation https://www.openssl.org/docs/man1.0.2/ssl/SSL_CTX_set_tmp_dh.html
...
SSL_CTX ctx = SSL_CTX_new();
...
/* Set up ephemeral DH parameters. */
DH *dh_2048 = NULL;
FILE *paramfile;
paramfile = fopen("dh_param_2048.pem", "r");
if (paramfile)
dh_2048 = PEM_read_DHparams(paramfile, NULL, NULL, NULL);
fclose(paramfile);
else
/* Error. */
if (dh_2048 == NULL)
/* Error. */
if (SSL_CTX_set_tmp_dh(ctx, dh_2048) != 1)
/* Error. */
...
Who is responsible to free the memory allocated for the DH parameter?
Do I need to call DH_free(dh_2048) after the SSL_CTX is destroyed or if SSL_CTX_set_tmp_dh returns an error?
