Subject: [PATCH 1/3] scsi: aic7xxx: remove set but not used variable 'tinfo'

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

drivers/scsi/aic7xxx/aic7xxx_osm.c: In function
‘ahc_linux_target_alloc’:
drivers/scsi/aic7xxx/aic7xxx_osm.c:567:30: warning:
variable ‘tinfo’ set but not used [-Wunused-but-set-variable]

It is never used, and so can be removed.
