Hi Alexandre,

As mentioned in the mail archive referred, the GB Codec driver that is
currently available in kernel tree is dependent on qualcomm audio
driver. And some time later I made some minor modifications to remove
the unnecessary dependencies. However, I missed to share the same with
the community :(

Thanks to you for triggering the thread. Now, I could retrieve my local
changes and I have been in the process of updating it again to make it
compatible with latest kernel.

I'm planning to share the same here in the next few days.  I'll mark you
in CC to seek your review comments as well.

In case, I'm unable to make those changes to the staging tree, I would
also recommend to drop this code. Kindly let me know your opinion.
