The only actionable feedback I have seen is that the header file
changes should be in uapi, which is done in patches 2 and 3.

Other than that, there was a question if this is a Linux issue or
a Chromebook issue (it appears that only Chromebooks shipped with
v4 configuration files). I took that as rhetorical since upstream
kernels (at least v4.4 and v4.5) support topology v4 configuration
files, and it should not matter which products shipped using those.
