Subject: [PATCH 09/22] m68k/mac: oss - Modernize printing of kernel messages

Convert from printk() to pr_*().

  - Introduce helpers for printing debug messages, incl. dummies for
    validating format strings when debugging is disabled,
  - Convert from printk() to pr_*(),
  - Drop superfluous casts,
  - Add linebreaks before opening braces of function bodies.
