In ips_init_phase1(), most early-exit error paths use ips_abort_init(), which properly releases ioremap_ptr. However, the path where kzalloc() fails does not go through ips_abort_init() and therefore skips unmapping ioremap_ptr, leading to a potential resource leak.
Add the missing iounmap() call in this specific failure path.
