Subject: [PATCH net] net/act_pedit: fix an error code
Date: Wed, 14 Jun 2017 13:29:31 +0300 [thread overview]
Message-ID: <20170614102930.GH29394@elgon.mountain> (raw)
I'm reviewing static checker warnings where we do ERR_PTR(0), which is
the same as NULL. I'm pretty sure we intended to return ERR_PTR(-EINVAL)
here. Sometimes these bugs lead to a NULL dereference but I don't
immediately see that problem here.
Fixes: 71d0ed7079df ("net/act_pedit: Support using offset relative to the conventional network headers")
