Merge tag 'driver-core-4.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg KH: "Here are two small driver core / kernfs fixes for 4.9-rc3. One makes the Kconfig entry for DEBUG_TEST_DRIVER_REMOVE a bit more explicit that this is a crazy thing to enable for a distro kernel (thanks for trying Fedora!), the other resolves an issue with vim opening kernfs files (sysfs, configfs, etc.) Both have been in linux-next with no reported issues" * tag 'driver-core-4.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: driver core: Make Kconfig text for DEBUG_TEST_DRIVER_REMOVE stronger kernfs: Add noop_fsync to supported kernfs_file_fops

Say Y here if you want the Driver core to test driver remove functions
by calling probe, remove, probe. This tests the remove path without
having to unbind the driver or unload the driver module.
