I think this patch should be handled with patches[1].
[1] https://lkml.org/lkml/2017/2/14/655

I think that one maintainer among following subsystems
(mfd, chrome h/w platform, rtc and extcon)
will apply their git repository, and then one maintainer
will send the pull request of immutable branch for these patches.
