Subject: scsi: target: Remove unused variable 'tpg'
Git-commit: dd06a40201fe8a4db8071b4939fafc5905557b01
Patch-mainline: v5.9-rc1
References: bsc#1177393
Gcc reports warning as follows:
drivers/target/target_core_pr.c:1162:26: warning:
variable 'tpg' set but not used [-Wunused-but-set-variable]
1162 | struct se_portal_group *tpg;
| ^~~
After commit 63c9ffe473d3 ("scsi: target: Check enforce_pr_isids during
registration"), 'tpg' is never used. Remove it to avoid build warning.
