This patch removes unneeded return variables, using only
'0' instead.
It fixes the following warning detected by coccinelle:
./drivers/scsi/ipr.c:9508:5-7: Unneeded variable: "rc". Return "0" on
line 9524

As it's always returning 0 this is dead code as well:
rc = ipr_probe_ioa_part2(ioa_cfg);
if (rc) {
__ipr_remove(pdev);
return rc;
}
I think:
- static int ipr_probe_ioa_part2(struct ipr_ioa_cfg *ioa_cfg)
+ static void ipr_probe_ioa_part2(struct ipr_ioa_cfg *ioa_cfg)
is the right thing to do if you really want to touch it.
