Subject: [PATCH] scsi: smartpqi: remove set but not used variable 'ctrl_info'
Git-commit: 1c6294858950a3cc609570f050734e1492e6a155
Patch-mainline: v5.5-rc1
References: bsc#1156632,jsc#SLE-8633

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

drivers/scsi/smartpqi/smartpqi_init.c: In function 'pqi_driver_version_show':
drivers/scsi/smartpqi/smartpqi_init.c:6164:24: warning:
 variable 'ctrl_info' set but not used [-Wunused-but-set-variable]

commit 6d90615f1346 ("scsi: smartpqi: add sysfs entries") added it but
it was never used. Also remove variable 'shost'.
