Sounds good! We have all the patches. Apart from the patch you are
reviewing in this thread there is
http://linux-speakup.org/pipermail/speakup/2017-April/060645.html
which is not yet signed off (we haven't had feedback on decext).

I will now get latest staging-next from kernel source, just to be sure
that patches all apply cleanly.

Do you want me to post all of them here as one patch set? Because since
I last posted, one of them has been upstreamed.
