Subject: [PATCH 03/20] scsi: lpfc: lpfc_nvme: drop useless LIST_HEAD
Date: Sun, 23 Dec 2018 09:56:58 +0100	[thread overview]
Message-ID: <1545555435-24576-4-git-send-email-Julia.Lawall@lip6.fr> (raw)
In-Reply-To: <1545555435-24576-1-git-send-email-Julia.Lawall@lip6.fr>

Drop LIST_HEAD where the variable it declares is never used.

These were introduced with the file, but were not even used
at that time.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
identifier x;
@@
- LIST_HEAD(x);
  ... when != x
// </smpl>

Fixes: 01649561a8b4b ("scsi: lpfc: NVME Initiator: bind to nvme_fc api")
