Merge tag 'driver-core-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg Kroah-Hartman:
"Here are some small driver core and firmware fixes for 4.17-rc3
There's a kobject WARN() removal to make syzkaller a lot happier about
some "normal" error paths that it keeps hitting, which should reduce
the number of false-positives we have been getting recently.
There's also some fimware test and documentation fixes, and the
coredump() function signature change that needed to happen after -rc1
before drivers started to take advantage of it.
All of these have been in linux-next with no reported issues"
