Subject: [ndctl PATCH 5/5] ndctl, test: fix a resource leak in check_smart_threshold
Date: Fri, 10 Aug 2018 16:56:24 -0600	[thread overview]
Message-ID: <20180810225624.32383-6-vishal.l.verma@intel.com> (raw)
In-Reply-To: <20180810225624.32383-1-vishal.l.verma@intel.com>

Static analysis reports that we leak ndctl_cmd in the above function.
Fix by adding the cmd_unref to the exit path in the
__check_smart_threshold macro.

Cc: Dan Williams <dan.j.williams@intel.com>
