I've given this new revision a quick test; sorry for the delay.  With this
revision, when using "model=fujitsu-jwse" things seem to be working pretty
well.  In particular, the updates you mention greatly improve usability; the
lack of automatic interaction between mixer controls makes it much easier to
use and understand.

I think everything is present and accounted for in this latest revision. 
Thanks for your work on this.

The only slightly odd thing I noticed was that whenever the driver is loaded
the "headphone mic jack mode" defaults to "mic bias 80pc", rather than "line
out" or "headphone" which I would have expected.  Obviously this can be
manually or automatically overridden after module load, but in many ways it
would be good if it defaulted to one of the output modes (given that the
jack's primary purpose is for output).

Where does this leave us now?  Is the "fujitsu-jwse" a permanent thing, or
will the respective changes be rolled into something more generic?
