Subject: [PATCH v4 01/14] scsi: fnic: Replace shost_printk with dev_info/dev_err
Sending host information to shost_printk
prior to host initialization in fnic is unnecessary.
Replace shost_printk and a printk prior to this
initialization with dev_info and dev_err accordingly.

Changes between v1 and v2:
Incorporate review comments from Hannes:
Replace pr_info with dev_info.
Replace pr_err with dev_err.
Modify patch heading and description appropriately.
