Not true at all, the in-linux-next tree builds just fine with this
patch.  In fact, it's now in linux-next already.

Yes, but sometimes, especially for trivial patches, the maintainer is
routed around and patches go in through other trees.

Remember a maintainer is not someone who can say "no" to all patches
that comes in, sorry, we don't work that way.

As your stuff is now in the kernel, I would recommend dropping your
external tree.  It will only cause more problems in the future.
