Merge this as you would any other patch. If you are concerned with integration
with a non-mainline patchset I would encourage you to seek advice from
whoever provides that patchset. This code is aimed at mainline and is intended
to function in a mainline environment.

You should not be using the Wolfson repositories to track ASoC
development. Use the repository listed in MAINTAINERS.

Documentation/sound/alsa/soc, the changelogs and the code.

ASoC has been a part of the standard Linux kernel since 2.6.21. Unless
your kernel is exceptionally old it will already contain ASoC.

I can't really comment on a specific version of an out of tree patch set, the
Wolfson tree contains only a few unmerged changes to support Wolfson
devices. You should either compare the code yourself or ask the ucLinux
community to explain the changes they've made to the standard Linux
