From e336ed9647b06e3bb52995dbc51101cbdf39f2a2 Mon Sep 17 00:00:00 2001 From: Mathias Krause Date: Tue, 5 Feb 2013 18:19:14 +0100 Subject: crypto: user - fix empty string test in report API The current test for empty strings fails because it is testing the address of a field, not a pointer. So the test will always be true. Test the first character in the string to not be null instead.
