Why the extra blank line?

And what is userspace going to do with this noise?  Is this an error?
Just normal operation?  A device should never be saying anything to the
log for normal boot functionality.  When is this called?

And no need for the "cpu_capacity:" right?  Shouldn't the pr_info() line
handle the prefix for you?
