From: YueHaibing
Date: Fri Oct 26 2018 - 03:18:09 EST


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
fa222db0b036 ("scsi: hisi_sas: Don't lock DQ for complete task sending")
