Subject: [PATCH v19 03/15] clocksource/drivers/arm_arch_timer: Improve printk relevant code
From: Fu Wei <fu.wei@...aro.org>
This patch defines pr_fmt(fmt) for all pr_* functions,
then the pr_* doesn't need to add "arch_timer:" everytime.
According to the suggestion from checkpatch.pl:
(1) delete some Blank Spaces in arch_timer_banner;
(2) delete a redundant Tab in a bland line of arch_timer_init(void)
No functional change.
