Subject: [PATCH 01/16] clocksource: arm_arch_timer: clean up printk usage
Date: Wed, 19 Apr 2017 17:44:18 +0100 [thread overview]
Message-ID: <1492620273-30037-2-git-send-email-mark.rutland@arm.com> (raw)
In-Reply-To: <1492620273-30037-1-git-send-email-mark.rutland@arm.com>
From: Fu Wei <fu.wei@linaro.org>
Almost all string in the arm_arch_timer driver duplicate an common
prefix (though a few do not). For consistency, it would be better to use
pr_fmt(), and always use this prefix. At the same time, we may as well
clean up some whitespace issues in arch_timer_banner and
arch_timer_init.
No functional change.
