Subject: [PATCH -next] scsi: megaraid_sas: remove set but not used variables 'host' and 'wait_time'
Date:   Sat, 25 May 2019 20:42:02 +0800
Message-ID: <20190525124202.8120-1-yuehaibing@huawei.com>

Precedence: bulk

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

drivers/scsi/megaraid/megaraid_sas_base.c: In function megasas_suspend:
drivers/scsi/megaraid/megaraid_sas_base.c:7269:20: warning: variable host set but not used [-Wunused-but-set-variable]
drivers/scsi/megaraid/megaraid_sas_base.c: In function megasas_aen_polling:
drivers/scsi/megaraid/megaraid_sas_base.c:8397:15: warning: variable wait_time set but not used [-Wunused-but-set-variable]

'host' is never used since introduction in
commit 31ea7088974c ("[SCSI] megaraid_sas: add hibernation support")

'wait_time' is not used since commit
11c71cb4ab7c ("megaraid_sas: Do not allow PCI access during OCR")
