Jiri Slaby dd3307a8b3 xtensa: ISS: don't panic in rs_init ... [ Upstream commit 23411c7200 ] While alloc_tty_driver failure in rs_init would mean we have much bigger problem, there is no reason to panic when tty_register_driver fails there. It can fail for various reasons. So handle the failure gracefully. Actually handle them both while at it. This will make at least the console functional as it was enabled earlier by console_initcall in iss_console_init. Instead of shooting down the whole system. We move tty_port_init() after alloc_tty_driver(), so that we don't need to destroy the port in case the latter function fails.
