This is a device bug, not a kernel one. The ideal fix will come from the
device's vendor to bring itself into protocol complaince.

We do work around these types of problems when necessary, but we usually want a
statement from the vendor that they can't/won't fix it before we create new
quirks to maintain. The vendor has said they are investigating this and will
update with their conclusions. As far as I know, the ball is still in their
court.
