Subject: [PATCH 10/22] m68k/mac: psc - Modernize printing of kernel messages
Date: Wed, 7 Dec 2016 16:09:08 +0100 [thread overview]
Message-ID: <1481123360-10978-11-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.
