Steffen Maier c8bba14435 zfcp: bring back unit sysfs attributes for automatic LUN scan ... Through sysfs attributes, zfcp unit objects provide a trigger for manual LUN recovery and export information for problem determination. With commit f8210e3488 "[SCSI] zfcp: Allow midlayer to scan for LUNs when running in NPIV mode" and when attaching SCSI devices through this new optional method, no more zfcp unit objects are allocated for such SCSI devices. Hence, the above-mentioned trigger and information were missing. The information and context is located in SCSI transport device data since b62a8d9b45 "[SCSI] zfcp: Use SCSI device data zfcp_scsi_dev instead of zfcp_unit" 57c237731b "[SCSI] zfcp: Add zfcp private struct as SCSI device driver data" Hence, introduce the trigger and the information unconditionally for all SCSI devices attached through zfcp. We prefix the attribute names with 'zfcp_' to prevent collisions and to avoid mix-ups such as with the common 'state' attribute. Since some of the new attribute views do not need zfcp_port in the ZFCP_DEFINE_SCSI_ATTR helper macro, remove zfcp_port to avoid compiler warnings on unused variable. It's easy to open code the conversion from zfcp_scsi_dev to zfcp_port for the two already existing attributes hba_id and wwpn.
