Thanks. I'll take it for a spin ASAP.

TAINT_CRAP... Smirk. I didn't see that one in the docs:
https://www.kernel.org/doc/html/latest/admin-guide/tainted-kernels.html

Oh wait... TAINT_CRAP is "C" => a staging driver has been loaded

The one issue I anticipate with "depends on BROKEN" is
when I add support for revision 2, which isn't broken.

Regards.
