Hi Alison,

No need to apologize -- both entries do exist in the specification, and it
took the review to see that nothing in the driver can produce them yet.

Agreed, and thanks Dave: the patch is dropped, please don't pick it up.  The
entries can come back with the code that can produce them -- chunked
maintenance input transfer, or Request Abort Background Operation support.

The out-of-bounds read is fixed on its own by 3/4, so a device that reports a
code the table does not describe is handled either way.

Thanks to you and Richard for the review.

Gaobin
