Nothing obviously wrong from a quick look...

Thanks a lot for doing this!
I believe we should cc Greg here.
BTW if you care about cpuled trigger... it would be cool to turn it into one
trigger and pass
a cpu number as a parameter. It is good to see this limit fixed, but real
solution is to
register one trigger per driver.
Best regards,
Pavel
