[PATCH 3.2 074/126] HID: usbhid: Add HID_QUIRK_NOGET for Aten DVI KVM switch

[Ben Hutchings]

3.2.85-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Laura Abbott <labbott@xxxxxxxxxxxxxxxxx>

commit 849eca7b9dae0364e2fbe8afdf0fb610d12c9c8f upstream.

Like other KVM switches, the Aten DVI KVM switch needs a quirk to avoid spewing
errors:

[791759.606542] usb 1-5.4: input irq status -75 received
[791759.614537] usb 1-5.4: input irq status -75 received
[791759.622542] usb 1-5.4: input irq status -75 received

Add it.
