Subject: device-dax: introduce 'struct dev_dax' typed-driver operations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In preparation for introducing seed devices the dax-bus core needs to be
able to intercept ->probe() and ->remove() operations.  Towards that end
arrange for the bus and drivers to switch from raw 'struct device' driver
operations to 'struct dev_dax' typed operations.
