[ Upstream commit 5f96f42b76e00e2871033745ff029056cc725c76 ]

"The DISK-SUBSYSTEM is a special model name returned when LUs
are not installed. For example, when LU#0 is not installed in "OPEN-"
models, LU#0 is detected as the DISK-SUBSYSTEM model":
https://marc.info/?l=linux-scsi&m=125424006417825

It's missing for HP XP rebranded arrays, "HP"/"OPEN-".
Only the HITACHI one is present:
