I see plenty of printk()s (or pr_xxx()s if this patch is applied after
the printk() -> pr_xxx() replacement) that are not converted to
dev_xxx() in this driver. If we start using dev_xxx() it should be used
consistently.

How about we convert all printk()s to pr_xxx()s first (what you do in
your first patch), including those you convert to dev_xxx() here, and
then we consider patching some of the drivers to use dev_xxx() instead
of pr_xxx().
