[PATCH] treewide: Convert clockevents_notify to use int cpu
Joe Perches
joe at perches.com
Wed Dec 10 15:28:53 PST 2014
As far as I can tell, there's no value indirecting
the cpu passed to this function via a void *.
Update all the callers and called functions from within
clockevents_notify.
Miscellanea:
Add pr_fmt and convert one printk(KERN_ERR to pr_err
