There is an inconsistency in the names for the HDMI/DP Jack control

There might be an impact for the user space (UCM). I will fix
the UCM configurations when this patch is applied.

Yes, that's a known problem, and I left them so far just for keeping
the already existing stuff working.
Won't this break the current Chromebooks user-space?
I would really expect to upgrade UCM configs for the recent kernels in
this case. I believe, those sort of issues are better to fix early
than lately. I know, the transition might cause a little issues, but
usually "do upgrade answer" will help. I don't think that we speak
about a large group of users here.
Well, that's obviously against our dont-breaking-user-space rule.
The UCM profiles have been widely used on Chromebooks, and they can't
upgrade easily.
So, I believe this is a case where we have to live with messes.
If we speak about Google's kernels, they can apply a revert (depends on their
upgrade/maintenance policy). If users use the standard Linux distributions,
then we are fine, don't we?
I would make an exception for the dont-breaking-user-space policy in this
case. I am sure that the UCM configs will stabilize quickly. And this bad jack
name is against our control name policy. It's just a bug.
