[PATCH 3/3] scsi: aic7xxx: remove set but not used variable 'targ'

From: yu kuai
Date: Thu Jan 16 2020 - 06:57:09 EST


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

drivers/scsi/aic7xxx/aic7xxx_osm.c: In function âahc_send_asyncâ:
drivers/scsi/aic7xxx/aic7xxx_osm.c:1611:28: warning: variable
âtargâ set but not used [-Wunused-but-set-variable]

It is never used, and so can be removed. In this case
scsi_transport_target_data() can be removed because of no caller exist.
