Pull EXTCON patches from Greg Kroah-Hartman:
"Here are some drivers/extcon/ patches that I forgot to have you pull
in the larger char/misc patchset from yesterday, for the 3.8-rc1
kernel.
Nothing major here, just some driver updates, and cleanups, all of
which have been in linux-next for a while now.
