No, it shouldn't.
Drivers normally get added to the mainstream kernel if the driver is stable
enough and somebody acting as maintainer requests to have it included. And,
then of course, Linus / Alan / ... need to accept it.

I'm maintaining this driver, but in spite of lots of requests to add it to
the mainstream kernels, I refused to do so. The reason is that some people
(ca. 5%) using this driver are having serious problems, which I have not
been able to track down so far. In the worst case, you can end up with data
corruption. (I could reproduce and fix some of the problems, but not the data
corruption one.) As that's not funny, I do not want the driver to be in the
mainstream kernel.

My version is on

I would be both amazed and pissed off if this would be the case.
Amazed because somebody was investing time to work on the driver and
potentially even fix problems.
Pissed off, because I think it's very bad to fix problems and not submit
the patches back to the official maintainers.

BTW, if somebody can provide a reasonable description of the chip
(TRM-S1040), the chances that I'd find the bug would increase a lot ...
