Indeed so maybe the word "fix" in commit subject is not proper because
there might be no error at all. My point is that current solution is a
little bit non-obvious and an error might happen. If we were sure that
register_console() is called only from other __init functions, then it
should be made also __init.

Best regards,
Krzysztof
