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" * tag 'char-misc-4.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: vme: Fix wrong pointer utilization in ca91cx42_slave_get auxdisplay: fix new ht16k33 build errors ppdev: don't print a free'd string extcon: return error code on failure drivers: char: mem: Fix thinkos in kmem address checks mei: bus: enable OS version only for SPT and newer
