[PATCH v6 03/10] clocksource/drivers/arm_arch_timer: Improve printk relevant code

fu.wei
2016-06-29T18:17:44Z

From: Fu Wei <fu.wei@linaro.org>

This patch defines pr_fmt(fmt) for all pr_* functions,
then the pr_* don't need to add "arch_timer:" everytime.

Also delete some Blank Spaces in arch_timer_banner,
according to the suggestion from checkpatch.pl.

No functional change.
