I have researched a little the patchwork entry and it makes me think that Sean
did post it as part of a series for MediaTek Bluetooth drivers to the mediatek
mailing list (which is why we can find it in patchwork):
https://patchwork.kernel.org/project/linux-mediatek/list/?series=&submitter=169671&state=&q=%5Bv5&archive=&delegate=
It wasn't discussed there and some other patches of the series have been merged
to other trees (e.g. for serdev core).
So I assume Sean is also waiting to get this patch upstream.
