4.5-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jiri Slaby <jslaby@xxxxxxx> commit 6798df4c5fe0a7e6d2065cf79649a794e5ba7114 upstream. When csw->con_startup() fails in do_register_con_driver, we return no error (i.e. 0). This was changed back in 2006 by commit 3e795de763. Before that we used to return -ENODEV. So fix the return value to be -ENODEV in that case again.
