Probably need Boris' perspective here.

There are some patches that just landed to tip/tip.git today which I 
believe the first patch needs to rebase on top of.

My thought is maybe:
1) We can get an immutable branch from tip/tip.git with the conflicting 
changes.

2) An Ack from x86 maintainers on the first patch.

3) ASoC merges immutable branch and takes the series through ASoC tree.
