Subject: HID: Add NOGET quirk for all NCR devices
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b8e98f1c47b743e56f8ebe21006199cefd577ce5;p=deliverable%2Flinux.git

HID: Add NOGET quirk for all NCR devices

Devices manufactured by NCR have userspace hiddev-based drivers,
which do all the necessary device querying by themselves. The devices
must not be queried directly by the generic HID driver, as reported by
NCR engineers.
