linux-next: build failure after merge of the powerpc tree

[Stephen Rothwell <sfr@canb.auug.org.au>]

Hi all,

After merging the nvdimm tree, today's linux-next build (powerpc
allyesconfig) failed like this:

Caused by commit

  84ad6e5cd3e8 ("leds/powernv: Add driver for PowerNV platform")

I suspect that the updates to a file were missed in the commit?

I have reverted that commit for today.
