From e2934ed183b94cff7626a517877ecc9bbe82cdc8 Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 17 Jan 2017 12:31:56 -0800 Subject: [PATCH] scsi: lpfc: Fix lpfc_wwn_set return code check When I reversed the patch to re-add the lpfc_soft_wwn parameter feature, it re-added code that had a long-standing bug. (that's what I get I guess :) As Dan Carpenter pointed out - error checks looked at wrong polarity. 0 is success, -errno is failure. Updated checks.
