Subject: [PATCH 08/22] m68k/mac: iop - Modernize printing of kernel messages
Date: Wed,  7 Dec 2016 16:09:06 +0100	[thread overview]
Message-ID: <1481123360-10978-9-git-send-email-geert@linux-m68k.org> (raw)
In-Reply-To: <1481123360-10978-1-git-send-email-geert@linux-m68k.org>

  - Introduce helpers for printing debug messages, incl. dummies for
    validating format strings when debugging is disabled,
  - Convert from printk() to pr_*(),
  - Add missing continuations,
  - Drop superfluous casts.
