Driver core patches for 3.12-rc1

Browse source 
Here's the big driver core pull request for 3.12-rc1.
 
 Lots of tiny changes here fixing up the way sysfs attributes are
 created, to try to make drivers simpler, and fix a whole class race
 conditions with creations of device attributes after the device was
 announced to userspace.
 
 All the various pieces are acked by the different subsystem maintainers.
