Subject: [PATCH] tools: firewire: nosy-dump: fix a resource leak in main()
Date: Wed, 13 Sep 2017 20:21:16 +0200	[thread overview]
Message-ID: <20170913182116.24694-1-martink@posteo.de> (raw)

If option_input and option_output is true two files are opened
consecutively. In case the second fopen() fails, let's fclose()
the first one before returning early.
