I don't have a problem with the chagne to the test, however, the patch
title has a typo in it for "disabled" that should be corrected. I've
ACK'd the other 2 patches, so you only need to resubmit this one with a
correct title.

Thanks,

Ah, I misunderstood when we talked earlier today. I thought the typo was in
the text of the start selftest. That is, it was part of the patch.

For a typo in the subject, I can make that fix when I pulled it in. I just
avoid touching content of the patch itself.

Care to ack it?

Thanks!
