Andy, in order to clear up any confusion that might arise later on, and
to maintain high the quality of both code and git meta-information I think
you should explicitly mention both in the commit info and commit message
that this is an upcoming product.

Also, instead of just "HP" in the commit proper, it should say something
like "Upcoming HP ZBook".

But that's just my advice, now you need to wait and hear Takashi's advice.

We should always strive toward striking a healthy balance between companies'
needs and the public nature of the development of the Linux kernel and ALSA.
Unfortunately that means some details of upcoming models may end up
catching up the attention of the specialized press.

I encourage you to look on the bright side and think of it as free PR ;)

Best Regards,
Geraldo Nascimento
