I wonder why you left Nicolas Reviewed-by but not the one from Angelo. Anyway 
when sending a new version, be sure to drop the reviewed-by tags if there are 
substantial changes in the patch. We can argue if changing the clock names is a 
substantial change or not. Maybe that's why you left just one reviewed-by tag ;)
I'm just joking, I'll add the other tag myself.

Applied thanks.
