Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

I assume all that is the result of commit aa27badd8972 ("Intel MIC Card
Driver for X100 family") from the char-misc tree.

I have disabled that driver for today (that commit did not revert
cleanly):
