pps: convert printk/pr_* to dev_* 2011-01-13T16:03:19+00:00 Alexander Gordeev lasaine@lvk.cs.msu.su 2011-01-13T01:00:52+00:00 7f7cce74105adf714bdc9357da3b6f06e019958c Since we now have direct pointers to struct pps_device everywhere it's easy to use dev_* functions to print messages instead of plain printks. Where dev_* cannot be used printks are converted to pr_*.

Using a direct pointer is much more easy (and safe as well).
