From: Akinobu Mita <akinobu.m...@gmail.com>
QEMU would not start when trying to create two UFS host controllers and
a UFS logical unit for each with the following options:
-device ufs,id=bus0 \
-device ufs-lu,drive=drive1,bus=bus0,lun=0 \
-device ufs,id=bus1 \
-device ufs-lu,drive=drive2,bus=bus1,lun=0 \
This is because the same ID string ("0:0:0/scsi-disk") is generated
for both UFS logical units.
To fix this issue, prepend the parent pci device's path to make
the ID string unique.
("0000:00:03.0/0:0:0/scsi-disk" and "0000:00:04.0/0:0:0/scsi-disk")
Resolves: #2018
Fixes: 096434fea13a ("hw/ufs: Modify lu.c to share codes with SCSI subsystem")
