Subject: [PATCH -next] scsi: megaraid_sas: remove set but not used variable 'cur_state'
Date: Sat, 25 May 2019 20:38:21 +0800	[thread overview]
Message-ID: <20190525123821.16528-1-yuehaibing@huawei.com> (raw)

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

drivers/scsi/megaraid/megaraid_sas_base.c: In function megasas_transition_to_ready:
drivers/scsi/megaraid/megaraid_sas_base.c:3900:6: warning: variable cur_state set but not used [-Wunused-but-set-variable]

It's not used any more since commit 7218df69e360 ("[SCSI]
megaraid_sas: use the firmware boot timeout when waiting for commands")
