Well, I've already merged HD-audio part, so any changes will be
incremental over it.

CS35L41 HD-audio stuff still won't work as of now with my tree alone
because of the lack of the ACPI patch.  So it's fine to merge those
changes to Mark's tree and break the stuff now, supposing it'll be
synced again before 5.17-rc1 pull request.  After it's merged to my
tree, you can submit the HD-audio fix, to be merged before rc1. 


thanks,

Takashi
