Ah, perfect, thanks.
When do you expect to send these on so that they end up in linux-next and eventually Linus's tree?
Note that it looks like something happened with the commit messages when you applied these. Specifically, the Fixes tags appears to now have a line break in them and there's also some random whitespace before your SoB:
Fixes: c3bf8e21

It's possible just the gitlab UI that's messed up, but perhaps you can double check before they hit linux-next, which should complain about this otherwise.
