Date
4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit e34ff8edcae89922d187425ab0b82e6a039aa371 ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/scsi/hisi_sas/hisi_sas_v1_hw.c: In function 'start_delivery_v1_hw':
drivers/scsi/hisi_sas/hisi_sas_v1_hw.c:907:20: warning:
variable 'dq_list' set but not used [-Wunused-but-set-variable]

drivers/scsi/hisi_sas/hisi_sas_v2_hw.c: In function 'start_delivery_v2_hw':
drivers/scsi/hisi_sas/hisi_sas_v2_hw.c:1671:20: warning:
variable 'dq_list' set but not used [-Wunused-but-set-variable]

drivers/scsi/hisi_sas/hisi_sas_v3_hw.c: In function 'start_delivery_v3_hw':
drivers/scsi/hisi_sas/hisi_sas_v3_hw.c:889:20: warning:
variable 'dq_list' set but not used [-Wunused-but-set-variable]

It never used since introduction in commit
