To remove that inconsistency make cpufreq_add_policy_cpu() execute
cpufreq_cpu_put() for the given policy before returning, which
decrements the driver module refcount so that it will be 0 after
__cpufreq_add_dev() returns.  Moreover, remove the cpufreq_cpu_get()
call from cpufreq_add_dev_symlink(), since both the policy refcount
and the driver module refcount are nonzero when it is called and they
don't need to be bumped up by it.

Sorry for creating so many problems but my concerns with this patch
aren't yet over :(

Should we increment policy refcount or kobj refcount for every cpu it
is used on? I think yes, that's probably the right way of doing it.

And so we simply can't remove calls to cpufreq_cpu_get() from
cpufreq_add_dev_symlink() routine and also from
cpufreq_add_policy_cpu()..
