From bc8d9d42573bef6e786d33a6115dc3e2df70a5da Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Tue, 3 May 2016 17:05:54 +0200 Subject: [PATCH] tty: vt, return error when con_startup fails 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.
