Merge tag 'char-misc-4.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver fixes from Greg KH:
"Here are some small char/misc driver fixes for 4.10-rc4 that resolve
some reported issues.
The MEI driver issue resolves a lot of problems that people have been
having, as does the mem driver fix. The other minor fixes resolve
other reported issues.
All of these have been in linux-next for a while"
