What is the likely time scale for getting a new version of bindgen
with the necessary bit field support?

We have probably missed the merge window for v6.7. So there is around
9 weeks to the next merge window. If a working bindgen is likely to be
available by then, we should not bother with a workaround, just wait.

If you think bindgen is going to take longer than that, then we should
consider workarounds. But we have no rush, its still 9 weeks before we
need working code.

Zooming out a bit. Is there any other in mainline Rust code, or about
to be submitted for this merge window code, using bit fields? I assume
that is equally broken?
