Subject: [PATCH] IB/IPoIB: Fix error code in ipoib_add_port()
Date: Thu, 13 Jul 2017 10:45:48 +0300 [thread overview]
Message-ID: <20170713074548.i6cgpjhmmcnvtd5c@mwanda> (raw)
We accidentally don't see the error code on some of these error paths.
It means we return ERR_PTR(0) which is NULL and it results in a NULL
dereference in the caller.
This bug dates to pre-git days.
