Thanks for your pointing it out and I totally agree with you. Actually, 
we are preparing 4.13 update for now and an another update will be 
followed up. As I answered above, I'll rebase this patch set onto the 
latest kernel.org mainline. Sorry for my misunderstanding of upstream 
process.

I've already cc'ed openbmc developers so they are also seeing this 
thread. Joel Stanley <joel@jms.id.au> is the openbmc kernel maintainer.
