Coincidentally I haven't touched this device/platform for months... until last
weekend where I noticed the same.  It does not apply cleanly and I had to solve
some conflicts:

https://github.com/SoMainline/linux/commit/8ec5d02eaffcec24fcab6a989ab117a5b72b96b6

I'll gladly resend this!

Note that I have one more unmerged leds patch around, that hasn't been looked
at either.  Would it help to send this once again, perhaps with more reviewers/
testing (Johan, would you mind taking a look too)?

Thanks!
