Along with Devfreq/Passive patchset, the patchset is merged in
devfreq for-4.7 tree.

https://git.kernel.org/cgit/linux/kernel/git/mzx/devfreq.git/log/?h=for-4.7

@Chanwoo: If there are commits to be merged by a tree other than Linux/PM,
please let me know. I'll send out pull-request soon.


Cheers,
