It's probably a good idea to do builds with clang at this point since apparently it can catch some cases that GCC doesn't. There's some documentation on how to do that here:
https://www.kernel.org/doc/html/latest/kbuild/llvm.html
The process is quite similar to using GCC and it has the advantage that clang ships with built-in cross-compilers, so less hassle setting things up.

Yes, the hte_return_t failures were my fault. Turns out due to some dependencies not being fulfilled my test builds didn't cover gpiolib character devices, so I didn't catch those.
I've not got a couple of configurations that I can build and a short script that will verify that all the necessary files have been built, so that should hopefully catch such issues in the future.
I had also pushed a fixed branch yesterday and it looks like today's linux-next built fine for HTE, so it's now included.
