Adding Greg in the To: list for his comments.

Hi Greg,
Incase you have not seen the previous mails in the thread, we were
discussing if mali driver code can be added to staging. Many benefits,
but the problem is that the userspace is closed and unless we have an
open userspace this cannot be merged with the main part of the kernel.
