Subject: [dpdk-dev] [PATCH] examples/kni: unchecked return value
Date: Mon,  9 May 2016 11:38:30 +0200	[thread overview]
Message-ID: <1462786710-22032-1-git-send-email-danielx.t.mrzyglod@intel.com> (raw)

Fix issue reported by Coverity.
Coverity ID 30692

If the function returns an error value, the error value may be mistaken for
a normal value.

In kni_free_kni: Value returned from a function is not checked for errors
before being used

Fixes: b475eb0bc400 ("examples/kni: new parameters")
