Daniel P. Engel 66df514b1d USB HID: add QUIRK_HIDDEV for Belkin Flip KVM 
Add HID_QUIRK_HIDDEV for the Belkin Flip USB KVM, which provides for software
control of switching via a HID class interface. It overloads three HID LED
usages, two of which aren't mapped in the ev_dev input subsection, and which it
doesn't make sense to map. In order to force the creation of a hiddev device
for controlling the Flip, this quirk flag is needed.
