Series merged on my stage tree, at:
https://git.linuxtv.org/media_stage.git/log/
I'll be merging it at media_tree (either for 5.13 or 5.14) after the
end of the merge window (likely next week).
Please let me know if you find any problems on it.
PS.: please notice that my stage tree can be rebased.
Regards,
Mauro
