Subject: [PATCH] net: caif: chnl_net: remove unnecessary null check in chnl_recv_cb
Date: Mon, 30 Oct 2017 17:47:14 -0500 [thread overview]
Message-ID: <20171030224714.GA31045@embeddedor.com> (raw)
container_of is never null, so this null check is unnecessary.
This code was detected with the help of Coccinelle.
