This isn't the right way to fix this actually.

The first pr_info is not terminated with a newline,
so the second printk should be printk(KERN_CONT or
pr_cont instead.

Ideally, you would make a different change.
There should be just one printk/pr_info.
Fewer messages, couldn't be interleaved with other
simultaneous output, easier to grep, etc...

I think something like this would be better:

 	if (phydev->link)
		pr_info("PHY: %s - Link is down\n", dev_name(&phydev->dev));
	else
		pr_info("PHY: %s - Link is up - %d/%s\n",
			dev_name(&phydev->dev),
			phydev->speed,
			phydev->duplex == DUPLEX_FULL ? "Full" : "Half");

or maybe use dev_info like this:

 	if (phydev->link)
		dev_info(&phydev->dev, "PHY: Link is down\n");
	else
		dev_info(&phydev->dev, "PHY: Link is up - %d/%s\n",
			 phydev->speed,
			 phydev->duplex == DUPLEX_FULL ? "Full" : "Half");

cheers, Joe
