Driver core update for 4.14-rc1

Browse source 
Here is the "big" driver core update for 4.14-rc1.
 
 It's really not all that big, the largest thing here being some firmware
 tests to help ensure that that crazy api is working properly.
 
 There's also a new uevent for when a driver is bound or unbound from a
 device, fixing a hole in the driver model that's been there since the
 very beginning.  Many thanks to Dmitry for being persistent and pointing
 out how wrong I was about this all along :)
 
 Patches for the new uevents are already in the systemd tree, if people
 want to play around with them.
 
 Otherwise just a number of other small api changes and updates here,
 nothing major.  All of these patches have been in linux-next for a
 while with no reported issues.
