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"
