[GIT PULL] ->driverfs_dev removal for 4.8

[Williams, Dan J]

Hi Jens, please pull from:

+AKA- git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm for-4.8/block

...to receive:

The removal of -+AD4-driverfs+AF8-dev in favor of just passing the parent
device in as a parameter to add+AF8-disk(). +AKA-See below, it has received a
+ACI-Reviewed-by+ACI- from Christoph, Bart, and Johannes.

It is also a pre-requisite for Fam Zheng's work to cleanup gendisk
uevents vs attribute visibility +AFs-1+AF0-. +AKA-We would extend device+AF8-add+AF8-disk()
to take an attribute+AF8-group list.

This is based off a branch of block.git/for-4.8/drivers and has
received a positive build success notification from the kbuild robot
across several configs.
