From 76e27a79eddb6279bbbc0ec840d66b753a9ba0f3 Mon Sep 17 00:00:00 2001 From: Daniel Wagner Date: Mon, 12 Jun 2017 12:50:54 +0200 Subject: ubi-utils: Return error code if command line option is unknown The tools in question will quit with an exit code 0 if the command line option was not recognized. By returning an error code a calling script has the possibility to distinguish between a real success and an invalid invocation. We need to return -1 instead of EXIT_FAILURE to be consistent with the other exit code places.
