All 3 of this series applied.

Thanks.  I like these patches as I can review them on a mobile phone.
(though then I have to remember to apply them later ;)

Hmm. I really need to update my own MAINTAINERS entries before that email
address goes away.  For reference, jic23@kernel.org is the right one.
Somehow updating these things is never urgent enough to get around to doing!

Thanks,

Jonathan
