Error description
When the device that syscons points to as the console does not exist upon boot up, cfgcon never sets the login path (also called the default path) in the console driver. This results in lscons -d returning "NULL". When init then starts getty on /dev/console, "NULL" is put into the utmp ut_line field. When the situation is finally resolved and the console is set up, it is not possible to get getty to work because of the "NULL" in the utmp file. This change will cause the entry with "NULL" to get reused properly when the console is finally set up correctly.
Local fix
