What is the reason behind this change?  It looks like it's to use the
latest and greatest function.

If so, please don't make these changes - we have on many occasions been
blamed for size of diffstat, churn, needless change, and this patch is
exactly that.

By all means fix printk's without KERN_ constants, possibly converting
them to pr_*, but don't go around replacing printk(KERN_* with pr_*(
without ensuring that there's a real benefit to the change.
