The Panda audio support is going via sound tree. It is in linux-next
already for couple of weeks now. The reason you have this reject is that
you don't have the audio support for Panda series, and a such upstream
does not have it either :( It is for 3.4 also.

If Liam would take this series that would be probably the way forward.
If he does not have objections.
Liam: I can create a branch for you to pull from as soon as all other
patch receives the needed acks...

Samuel: if Liam agrees is it possible for you to drop the twl6040
related patches from your for-next branch?

Thank you,
Péter
