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
