I get the impression from the mailing list discussion that upstream may
end up going a different way with this fix, but it looks safe enough so
I don't see any reason we can't use this version until that happens.

The patch was mangled by your mailer though, and I ended up grabbing the
patch from patchwork. Applied as "UBUNTU: SAUCE: (no-up) HID: Add quirk
for Lenovo Yoga 910 with ITE Chips" to artful and unstable, thanks.
