Subject: [PATCH 1/3] fnic: host reset returns nonzero value(errno) on success
Date: Thu, 12 Sep 2013 17:45:41 -0700	[thread overview]
Message-ID: <1379033143-1482-1-git-send-email-hiralpat@cisco.com> (raw)

From: Narsimhulu Musini <nmusini@cisco.com>

Fixed appropriate error codes that returns negative error number on failure,
and 0 on success. fnic_reset() is used directly by the fc transport callback
issue_fc_host_lip which requires a negative error number on failure.
