No, I didn't pick it up. The branch Angelo pointed to is just the branch 
I used to compile test your series, I haven't posted a PR for it.

Next week I'll try again with v14 to check if it passes all my compile 
tests, and if OK, then I'll post a PR.

Patches are picked up if I post a PR and they are marked as 'Under 
Review' in patchwork. When Mauro merges them in our tree, then the state 
goes to 'Accepted'.
