Actually not:

static int __dev_printk(const char *level, const struct device *dev,
                        struct va_format *vaf)
{
        if (!dev)
                return printk("%s(NULL device *): %pV", level, vaf);

        return dev_printk_emit(level[1] - '0', dev,
                               "%s %s: %pV",
                               dev_driver_string(dev), dev_name(dev), vaf);
}
