I'm afraid that this doesn't work.  The former entry with the vendor
17aa already hits and it's used as the matched quirk.

You'd need to create a chained quirk entry instead.

Also, this doesn't look right.  The vendor match should be put after
all Lenovo entries.  I guess the similar chained quirk is needed like
for Conexant.
