The whole situation has been very confused.

Your patch is out-of-date because it doesn't include the
US_FL_NEED_OVERRIDE flag for revisions 0x1000 - 0x9008.  Also, is it true
that US_SC_8070 is correct (if unnecessary) for all the QV cameras?  If it
is, we could simply have a single entry for all revisions that would
override both the subclass and protocol fields.
