I reduced it and filled an issue upstream:

    https://github.com/rust-lang/rust-bindgen/issues/3179

And I sent a potential patch to deal with this cleanly in a single
place (as long as the C headers allow for it, which in your case it
does), please see:

    https://lore.kernel.org/rust-for-linux/20250325184309.97170-1-ojeda@xxxxxxxxxx/

By the way, it wasn't UB, no? i.e. the UB one was the parsing patch on
the modules series, which we discussed roughly at the same time.

I hope that helps!

Cheers,
Miguel
