The function should return 0 on success, instead of err.
Addresses-Coverity-ID: 1493753 ("Identical code for different branches")
Fixes: 6a98d71daea1 ("RDMA/rtrs: client: main functionality")

Why to keep the if-statement? Has the following been considered?
diff --git a/drivers/infiniband/ulp/rtrs/rtrs-clt.c b/drivers/infiniband/ulp/rtrs/rtrs-clt.c
index 8dfa56dc32bc..a7f5d55f8542 100644

@@ -1587,8 +1587,6 @@ static int create_con_cq_qp(struct rtrs_clt_con *con)
* since destroy_con_cq_qp() must be called.
*/
- if (err)
- return err;
return err;
}
Thanks,
Bart.
