Prev: [PATCHv3 13/16] pps: capture MONOTONIC_RAW timestamps as well
Next: [PATCHv3 02/16] pps: declare variables where they are used in switch
From: Alexander Gordeev on 4 Aug 2010 17:20
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_*.
