Pull driver core fix from Greg KH:
"Here is a single patch being reverted to remove a feature that was
added in 4.10-rc1 that isn't quite ready for release.
It will be redone as a debugfs file instead of a sysfs file in the
future"
* tag 'driver-core-4.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
