Good news!

I've tested this patch series on the following devices:

- Chromebook Pixel 2013 ("link")
- Framework Laptop 11th Gen Intel Core ("hx20"), firmware revision 3.19
- Framework Laptop AMD Ryzen 7040 Series ("azalea"), firmware revision 3.05

It works as expected.
There is no detectable difference at runtime on Link, nor does the
driver appear to improperly bind any ACPI devices.
I cannot reproduce bus contention on hx20, even performing operations
that would consistently fail without this patch (e.g. long flash
reads).

Therefore, for the series:

Tested-on: link, hx20, azalea
