Subject: [Qemu-devel] [PATCH] scsi: Drop useless null test in scsi_unit_attention()
Date: Thu, 17 Jan 2013 13:07:47 +0100 [thread overview]
Message-ID: <1358424467-15293-1-git-send-email-armbru@redhat.com> (raw)
req was created by scsi_req_alloc(), which initializes req->dev to a
value it dereferences. req->dev isn't changed anywhere else.
Therefore, req->dev can't be null.
Drop the useless null test; it spooks Coverity.
