From dfea79004c54bc96143386d6ac22de500ba4f747 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Tue, 4 May 2010 22:41:34 +0200 Subject: remove ecb parameter from xdi_diff_outf() xdi_diff_outf() overrides the structure members of its last parameter, ignoring any value that callers pass in. It's no surprise then that all callers pass a pointer to an uninitialized structure. They also don't read it after the call, so the parameter is neither used for input nor for output. Turn it into a local variable of xdi_diff_outf().
