Thanks, but this needs to go in in two pieces, because cpufreq_start_governor()
in the mainline doesn't check cpufreq_suspended (the linux-next version of it
does that).
So the second part of the patch is needed in the mainline/stable to get rid
of false-positive WARN_ON()s and the first one can go in on top of the
previous linux-next changes.
Thanks,
Rafael
