Actually I did not.
The compile error has been introduced by this commit

commit 4e48afecd5ee3a394d228349fc1c33982e9fb557
Author: Mauro Carvalho Chehab <mchehab@s-opensource.com>

media: v4l2-async: simplify v4l2_async_subdev structure

Which is not in v4.15-rc8 on which I have based my work on.

As a general question, if I'm aiming to have my driver included in
next release, should I always base my work on linux-next or it depends
on sub-system/maintainers preferences?

Thanks
