Linus Torvalds 098c30557a Driver core patches for 4.10-rc1
Here's the new driver core patches for 4.10-rc1.
 
 Big thing here is the nice addition of "functional dependencies" to the
 driver core.  The idea has been talked about for a very long time, great
 job to Rafael for stepping up and implementing it. It's been tested for
 longer than the 4.9-rc1 date, we held off on merging it earlier in order
 to feel more comfortable about it.
 
 Other than that, it's just a handful of small other patches, some good
 cleanups to the mess that is the firmware class code, and we have a test
 driver for the deferred probe logic.
 
 All of these have been in linux-next for a while with no reported
 issues.
