  firmware: Correct handling of fw_state_wait() return value (2016-12-08 21:05:54 +0100)

----------------------------------------------------------------
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.
