  drivers: base: remove check for callback in coredump_store() (2018-03-23 18:08:02 +0100)

----------------------------------------------------------------
Driver core patches for 4.17-rc1

Here is the "big" set of driver core patches for 4.17-rc1.

There's really not much here, just a bunch of firmware code refactoring
from Luis as he attempts to wrangle that codebase into something that is
managable, along with a bunch of userspace tests for it.  Other than
that, a handful of small bugfixes and reverts of things that didn't work
out.

Full details are in the shortlog, it's not all that much.

All of these have been in linux-next for a while with no reported
issues.
