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

[Stephen Rothwell]

Hi Matias,

After merging the lightnvm tree, today's linux-next build (x86_64
allmodconfig) failed like this:

ERROR: "nvm_alloc_dev" [drivers/nvme/host/nvme-core.ko] undefined!
ERROR: "nvm_alloc_dev" [drivers/block/null_blk.ko] undefined!

Caused by commit

  3daf1adc80a8 ("lightnvm: let drivers control the lifetime of nvm_dev")

I have used the lightnvm tree from next-20160629 for today.
