No.  These should be converted to pr_debug as well.

The conversion was done via script and the script doesn't
convert printk(KERN_DEBUG to pr_debug to avoid changing output.

Let me know if you want another patch.

Also converted via a script.

If the string is split, it doesn't matter where it's split.
The split just makes it harder to use grep.

Personally, I think it's better to ignore the line length
of format strings completely.  Once it wraps in an editor,
it really doesn't matter how long the line is.

Of course, there are multiple strings in this file that
use dev_<level> that are split across lines that could be
converted as well so it's up to you if you want to leave
those as is.  Let me know if you want another patch to
integrate those dev_<level> format strings.
