Merge tag 'char-misc-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver updates from Greg KH: "Here's the big char/misc driver patches for 4.10-rc1. Lots of tiny changes over lots of "minor" driver subsystems, the largest being some new FPGA drivers. Other than that, a few other new drivers, but no new driver subsystems added for this kernel cycle, a nice change. All of these have been in linux-next with no reported issues" * tag 'char-misc-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (107 commits) uio-hv-generic: store physical addresses instead of virtual Tools: hv: kvp: configurable external scripts path uio-hv-generic: new userspace i/o driver for VMBus vmbus: add support for dynamic device id's hv: change clockevents unbind tactics hv: acquire vmbus_connection.channel_mutex in vmbus_free_channels() hyperv: Fix spelling of HV_UNKOWN mei: bus: enable non-blocking RX mei: fix the back to back interrupt handling mei: synchronize irq before initiating a reset.
