Merge tag 'driver-core-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH: "Very tiny pull request for 4.12-rc1 for the driver core this time around. There are some documentation fixes, an eventpoll.h fixup to make it easier for the libc developers to take our header files directly, and some very minor driver core fixes and changes. All have been in linux-next for a very long time with no reported issues" * tag 'driver-core-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: Revert "kref: double kref_put() in my_data_handler()" driver core: don't initialize 'parent' in device_add() drivers: base: dma-mapping: use nth_page helper Documentation/ABI: add information about cpu_capacity debugfs: set no_llseek in DEFINE_DEBUGFS_ATTRIBUTE eventpoll.h: add missing epoll event masks eventpoll.h: fix epoll event masks
