Driver core patches for 4.2-rc1

Browse source 
Here is the driver core / firmware changes for 4.2-rc1.
 
 A number of small changes all over the place in the driver core, and in
 the firmware subsystem.  Nothing really major, full details in the
 shortlog.  Some of it is a bit of churn, given that the platform driver
 probing changes was found to not work well, so they were reverted.
 
 All of these have been in linux-next for a while with no reported
 issues.
