Subject: scsi: zfcp: wire previously driver-specific sysfs attributes also to
fc_host
Patch-mainline: v5.7-rc1
Git-commit: 538c6e910baea9a94ba2a816c19c3e071892b49c
References: bsc#1158050
Manufacturer, HBA model, firmware version, and hardware version. Use the
same value format as for the driver-specific attributes. Keep the
driver-specific attributes for stable user space sysfs API.
