But we are already returning a few lines above:
271 result = CryptCreateHash(hProv, CALG_MD2, 0, 0, &hHash);
272 if (!result) {
273 /* rsaenh compiled without OpenSSL */
274 ok(GetLastError()==NTE_BAD_ALGID, "%08x\n", GetLastError());
275 return FALSE;
276 }
We will not get here if result = 0;
277 ok(result, "%08x\n", GetLastError());
278 if (!result) return FALSE;
So that last one is needless.
