Hi Greg,
In which branch do I see that ? I tried to find it in your char-misc
repo but couldn't find it.

Thanks,
Oded

It should be in the char-misc-linus branch of the char-misc.git repo on
git.kernel.org.  Note, I was in the air for a long time yesterday, so
the emails probably went out 8 hours before I was able to push out the
git repo, but it should all be synced up now.  Sorry for any confusion
there.
