Hi Simon,

Wow, that was quick. Thank you!

Yes. Probably we should activate the shiny new DEBUG_TEST_DRIVER_REMOVE
and if that passes, we should be safe.

OK. I'll try to have a look at those drivers nonetheless, because
rebasing these patches is a bit of a hazzle once new i2c slaves were
added to the busses. But I'll juest resend the patches along with my
fixes if I really can find the time.

I assume you mean 'porter' here.

Will you get access to these boards in the foreseeable future?

Thanks,
