Merge tag 'char-misc-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc updates from Greg KH:
"Here is the big set of char/misc driver patches for 4.17-rc1.
There are a lot of little things in here, nothing huge, but all
important to the different hardware types involved:
- thunderbolt driver updates
- parport updates (people still care...)
- nvmem driver updates
- mei updates (as always)
- hwtracing driver updates
- hyperv driver updates
- extcon driver updates
- ... and a handful of even smaller driver subsystem and individual
driver updates
All of these have been in linux-next with no reported issues"
