Merge tag 'driver-core-4.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
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: Revert "driver core: Add deferred_probe attribute to devices in sysfs"
